I like Tribute bands. The only one I've seen who I have issues with is the Bootleg Beatles and everyone else says they are great so I assume I can use the classic break up line "It's not you, it's me!" I can't even put my finger on what I don't like with them. It might be that they do the costume changes rather than stick with one era. But it's just a personal view. The Counterfit Stones were great when I saw them.
I do hate the way such issues become covers bands vs tribute bands vs originals bands. Yes, some originals bands aren't so original (& I would say like BigRedX this is always my personal preference), some covers bands aren't so hot and some tribute bands don't help the cause. Ultimately there are good and bad examples of each and on that note it is time to move on. I can see myself being in a Tribute band at some stage in the future purely as it is one musical experience I'm yet to have.
