Tonight's mystery artists before one performance had a producer come on stage and lecture the audience beforehand to show respect. Can you guess which band’s fans he was worried about??

NBC News Pop Culture tells the story according to Vince Calandra, who was a stage producer for "The Ed Sullivan Show," fear of out-of-control teens worried Sullivan enough that he showed up at the Saturday rehearsal -- something he never did -- to lecture the audience before the Beatles took the stage not for their sake either but worried that they wouldn’t be good to the other performers..

"He was saying things to the audience like 'Kids, you have to be respectful to our other performers, and if you're not, I'm gonna come out into the audience and take everyone's name and address and report you to your mothers and fathers.' Silly stuff like that," Calendra told TODAY.

According to Ed Sullivan’s webpage the show had the boys performed twice that evening once in the first half of the show and again in the second. His site states “Concerned that The Beatles’ shrieking fans would steal attention from the other acts that evening,

Ed Sullivan admonished his audience, “If you don’t keep quiet, I’m going to send for a barber.”

The site goes on to say, Hard as Ed tried to protect them, the other acts that night suffered from the excitement surrounding The Beatles. Numbered among those performers were impressionist Frank Gorshin, acrobats Wells & the Four Fays, the comedy team of McCall & Brill and Broadway star Georgia Brown joined by the cast of “Oliver!

Here is tonight's featured song plus a few of the acts that competed for the kids attention that night complete with a young Davy Jones as the Artful Dodger.
