Thanks Marc and Bob interesting stuff. I agree about brand names...I know of a few "used to be" big name groups that retain the "brand name" but have only one or sometimes no original personnel from the original band.
Evolution at its worst. Most of us are unable to put a name to the majority of band members anyway. Heck some people cannot even put a correct band name to hits.
Even more reason to accept that cover and tribute bands have their place. I adopt the opinion that as long as the guys can play and entertain an audience they deserve to make a living.
I have seen a number of original bands who cannot.
