Re: To be great in the UK
I think you might be better off booking some gigs in some small clubs around the UK. Listen to what's hip in the UK music scene at the moment and time your "arrival" perfectly. E-mail some of your tunes to club owners and get the ball rolling. Don't just move to London and expect gigs. Spend a year or two visiting as often as you can with your band and see what the reaction is like. You might be better off trying out smaller and cheaper cities other than London too, such as Birmingham, Cardiff or Bristol. Anything outside London as London is the most competitive and largest, not to mention expensive.
