Sticky Fingers and Colorado Clubs have live rock music, both have groups on facebook you can search for address/info. There's also a rock bar on the main Bar Street (Orfandinou) though I can't remember what it's called.

Thanx a million, you wouldn't know the best place to hire a motorbike would you

Not sure sorry though there are lots of hire companies around. Just check your insurance before you go as most will only cover you up to a certain CC.
