"should have known better
update: even better… check this out:
I read that when the Beatles were recording “A Day in the Life”, George Martin had the idea of bringing in hundreds of people to play random instruments for the break in the song. It turned into an orchestra of the mad, with people donning funky eyeglasses, weird costumes, and one guy even played his cello with the hand from a gorilla costume.
Anyway, you get a glimpse of the party in this YouTube vid. Awesome stuff.
