SCHOTT, Justice Ad Hoc.1
Defendant was convicted of armed robbery and sentenced as a multiple offender to 197 years 11 months imprisonment. In his appeal from his conviction and his sentence he relies on three assignments of error.
PROCEDURAL BACKGROUND
Defendant, Frank Smith, and one Marvin Miller were jointly charged with committing armed robbery of Mrs. Joseph Santopa-dre on October 9, 1975. They both pleaded not guilty, and following a trial by jury they were found guilty and sentenced in January, 1976. In April, 1978, this court reversed the convictions and remanded the case. State v. Smith, 357 So.2d 524 (La.1978). On the date of the trial now under review, May 21, 1979, Miller withdrew his plea of not guilty, entered a plea of guilty as charged, and was remanded to prison to await sentence. Following the trial the jury unanimously found defendant Smith guilty as charged. The multiple offender hearing and sentencing took place on December 18, 1979.
FACTS
On October 9, 1975, at about 1:15 PM Mrs. Santopadre was in her Tiptop Shoe Repair store on Carrollton Avenue in New Orleans when two men entered. She was alone in front of the store, her son Chris Santopadre was in a back room, and an employee, George Cox, had gone to a shop next door. One of the men stuck a gun in her stomach and announced a holdup, whereupon she immediately went to her cash register, accompanied by the two robbers. As she was handing money to them and one of them was reaching over grabbing the rest of the money, her son came to the front of the store and the man with the gun forced him to lie down on the floor. A few moments later Cox came back into the store, he was ordered to lie down by the other gunman, and the two robbers then *1112fled from the store with the money. Chris ran out of the store after them and saw them getting into a yellow Volkswagen automobile whose license plate he took down. This information was immediately relayed to the police. A short time later the vehicle was stopped some distance and on the other side of the Mississippi River from the scene of the robbery. It was being driven by one David Singleton and a search of the car disclosed one of the weapons used in the holdup. On an anonymous tip the police subsequently arrested defendant and Miller.
A few days later the police brought a stack of black and white photographs containing defendant’s photograph and Mrs. Santopadre and her son picked the defendant’s photograph from the stack. In a subsequent lineup at police headquarters Chris Santopadre picked out defendant Smith and again made a positive identification. Although Mrs. Santopadre did not identify defendant Smith at the lineup she and her son both made positive identifications of defendant in court.
ASSIGNMENT OF ERROR NO. 1
By this assignment defendant contends that reversible error was committed when the clerk of the court was permitted to testify that co-defendant Miller had pleaded guilty to the offense on the morning of the trial.
After the trial the prosecutor announced that he was calling Miller to the stand as a witness. Miller, through his attorney, informed the court that he would not testify but would take the fifth amendment against self incrimination. The prosecutor argued that his plea of guilty had removed the grounds for invocation of the fifth amendment, and Miller then attempted to withdraw his plea of guilty which was denied by the court. Miller’s defense counsel informed the court that he had advised Miller that he would not be required to testify and that this was one of the prime considerations for his entering a plea of guilty, and the defense counsel made it clear that Miller, if placed on the witness stand, would take the fifth amendment. Thus, the trial court could not compel Miller to testify pursuant to State v. Berry, 324 So.2d 822 (La.1975).
When the prosecutor announced his intention to put the court clerk on the stand to testify to Miller’s plea of guilty, the only objection made by defendant was that this testimony was not the best evidence since Miller himself was available to testify in person. Defendant did not object that the clerk’s testimony was per se inadmissible because of its irrelevancy to the guilt of the defendant Smith as he now argues in this court. Thus, this argument is untimely and is not properly before us. State v. Motton, 395 So.2d 1337 (La.1981).
In addition, the prohibition against the use of a plea of guilty by an accomplice at the trial of the other accomplice is not absolute but is sometimes relaxed according to the particular facts and circumstances of the case. United States v. King, 505 F.2d 602 (5th Cir. 1974). Co-defendant Miller was charged jointly with defendant in the bill of information which was read to the jury, he was discussed and identified by all of the witnesses as being an accomplice, and he was even brought into court physically for the purpose of identification by the witness Cox. The jury doubtless had a right to know what happened to Miller when they were charged with the grave responsibility of considering defendant’s fate.
Finally, when all of the evidence is considered in this case, where the victim and her son testified clearly and unequovieally that this defendant robbed her at gun point and there was absolutely no question about their identification of him, the testimony of the court clerk, even if error, was hardly prejudicial, but simple harmless error. Applying the principles of State v. Gibson, 391 So.2d 421 (La.1980) we can conclude without any difficulty that there was no reasonable possibility that the court clerk’s testimony contributed to the conviction. It took place at the tail end of a trial which contained overwhelming evidence to convict *1113this defendant of the offense charged beyond the shadow of a doubt.
ASSIGNMENT OF ERROR NO. 2
By this assignment defendant complains that his rights were prejudiced because the court did not permit him to call David Singleton as a witness in his behalf. Singleton announced that, if called, he would take the fifth amendment. Thus, it would have been error for the trial court to place him on the witness stand. State v. Berry, 324 So.2d 822 (La.1975).
ASSIGNMENT OF ERROR NO. 4
By this assignment defendant contends that his constitutional rights were violated during the multiple offender proceedings because there was no showing that the guilty plea he entered in the previous hearing was taken in accordance with the requirements of Boykin v. Alabama, 395 U.S. 238, 89 S.Ct. 1709, 23 L.Ed.2d 274 (1969). However, this objection and argument were not made at the trial. The only objection made at the trial had to do with the authenticity of evidence and consequently defendant is deemed to have waived his argument with respect to the guilty plea at the previous conviction. State v. Holden, 375 So.2d 1372 (La.1979).
Accordingly, the conviction and sentence are affirmed.
