James Corden pulled a stunt in a small pub where, if you picked a Beatles song on the jukebox, instead of the record playing a curtain would open, and Sir Paul McCartney and his band would play the song. Then the curtain would close.
Then ensuing mob of (well-behaved, deliriously happy) fans rushing to the pub was videotaped as well.
Growing up, I always found it slight strange that this big global name was playing down the road.
