As a hobbist who likes to make sure it's fun while paying for itself ...
Band 1, I'd like to see video of them first also, but sounds like a band I could enjoy if the singers, among other things are good.
Band 2, four hour rehearsals ? Fair enough if they've a big list of agreed numbers to get through to make sure they work, would need to know the rest of the band had also done homework. Not really for me (although classic rock covers I do enjoy) however it's an honest ad, could be a good bunch of chaps having good fun with no fixed agenda, so great if it's what your after .
