Go for it Beefy!
Some notes from the local perspective -
Classic rock goes down a storm in our neck of the woods, sound quality isn't that important, but visuals are - (needless to say, my band did pop/indie, had a great PA, didn't dress up and had no lights of our own ).
Sweet FA are flavour of the moment with most pub landords at the moment as they do the whole glam rock dressing up thing and everyone knows at least 90% of the set, plus they've got a bit of a following so landlords know they'll get some extra punters who wouldn't normally set foot in their pub.
Basically think "entertainer" rather than "musician" and you'll have a successful covers band in the West kent / East Sussex area.
