Interesting thread. \was playing a bluesy-type band a few years ago and I brought in a tenor and alto sax. We needed a few original numbers to flesh out the set and I offrered a fast, Motown-flavoured song I had written several years beforehand. Rehearsed the set and all going well, though the tenor saxophonist kept dropping out during my tune. Come the gig, all going well and we get to the song in question and the Janice Joplinesque singer announces it, says she hates it and the band steams in regardless. Suddenly, I am aware of no guitar! I look to my right and the guitarist is standin staring into space!! Then, during teh sax break, I can't hear any harmonies and look over to see the tenor player looking like he's sh*t himself!
Set over, I barrack the three culprits for pulling a stunt like that live! At no point was it even hinted at rehearsals that the singer & guitarist didn't like the song. On questioning the guitarist why he didn't like it he said "Cos it's got more than three chords!" The tenor player simply forgot his lines and sh*t it! The band didn't last long after that.
