As a corrective to all the glowing speeches from divas and the rapturous adulation of their fans, Bill Bailey (don’t miss his Love song!) recalls:

I was at a Whitney Houston gig, it was supposed to start at three—finally at four o’clock she comes on stage and says,
“I just wanna say, I love each and every one of you!”
and this big black guy next to me shouts,
“Sing, bitch!”

This is a metaphorical version of the fan hitting the shit.
