What is important is that any publicity, including web site, includes both. When people are searching the web for a band, those who don't know what a ceilidh is will search for barn dance, those that do will search for ceilidh. You don't need to have either in the band's name, that said, we do and we pick up loads of work, partly because we have our web site coded so that search engines will pick up both categories and partly because we get repeat bookings and recommendations - always make sure that when you do a gig, you have some flyers or cards to give if asked for them. If you don't have any sound samples on your web site, then you need to make sure that you have some CDs to send out or to give on request.
