To be honest I don't go to pubs that have bands very often, simply because they usually play The Same Old Songs!
I'd be far more into it if the covers were more interesting, but that by definition would make it less crowd pleasing...
However, I'd be very happy if a covers band started with a Spizz Energi medlay (Red and black, SoldierSoldier,Captain Kirk), then something like He's Frank by the Monochrome Set followed by Something Better Change, Bowie's DJ and Boys, Funkadelic's Who says a rock band, and then Pumpme up by Trouble Funk. I'd be amazed too!
