I've seen a performer falling off chair drunk, singing so flat that the other members of the band played louder to cover the singer... trouble is, that just encouraged the singer who sang louder and flatter than before. The applause wasn't so much lack-lustre as just lacking...

Then there was the concert in Saffron Walden by June Tabor.. she was late for her sound check, her pianist complained about the Steinway Grand piano saying he couldn't play it (he was right, he couldn't), her fiddler pranced around with that 'I'm shagging the talent, don't you wish you were me' attitude, they kept the audience waiting outside in the October rain for 45 minutes, she refused entry to a disabled lady who just wanted to come in for shelter and acted all surprised when half the audience didn't return for the second half. And none of the missed notes on the piano were due to the sound man.

For sheer rudeness JT gets my vote (with my feet) every time.
