Do it, its a paying gig ! Aan as has been said, if you aint playing....
I got nothing against tribute acts, covers bands, whatever. better than kareokes and discos. What about tributes to dead bands/artistes. Dr Feelgood - for example - still gigging, same material, but with no original members, is that a tribute band operating under false pretences all over the world ?
What about tributes to bands that only did material written by others, cant think of an example, but you get my drift ?
Its all good. I always said I wouldnt do covers and workie clubs when I first started, done both in the end. Wouldnt wanna do workies again though.
