Many thanks for all that information and your time.
Yes our major act is a 'legendary star' (altho' that word is so bandied about now, it has lost it's real meaning) in another country and although not known outside of that area has an incredible track record and performance record. Right up to today his shows with his own band, are near full houses in the biggest clubs, with excellent critiques. It's been the same story for many many years.
Anyway not here to bore you or sell anything, just tyrying to get as much a 'feel' for the market we are trying to get into.
Once again your inforamtion is really appreciated.
