My band has been going three years, in which time we have done 50 gigs and used 16 people. As a blues band we seemed to cope well. Until November just gone, I was the only person never to have been depped.
I lined up a replacement but despite six months notice he cried off with a family commitment. The others lined up someone equally good who then got hospitalised. The third choice was apparently awful.
I returned, and after one gig the singer and the drummer both quit.
Not sure what this proves… answers on a postcard!
