Yay for 2 seconds of googling the exact thing you asked.
It wasn't a song.
quote:
On November 4, 1963, the Beatles played in front of the Queen at the Royal Command Variety Performance. The scene is immortalized in the Anthology video (The Beatles Anthology Collector's Set). Before playing their final number, John asked the audience for their help in the next number, and said, with a hesitant smirk: "The people in the cheaper seats, clap your hands... and if the rest of you would just rattle your jewelry." The camera pans to the Queen, who seems confused more than anything. The Beatles then launched into the raucous "Shout!". You can hear it on the Anthology CDs.
