When worlds collide

Just saw a comercial for a concert with ZZ Top, The Pretenders, and Stray Cats. While I respect musically all three acts, and all of them are very very good at the genres they have chosen, does the promoter really think that fans of one band will like the others? I haven't seen a more ill-concieved concert lineup since the hilarious Manson-Hole tour of a few years ago. Now that was a fun concert.
