This subject is one that is so vast it would take days to tell you the possibilities. The basis ones such as the D.J. and or a small or large band are typical. Ever think of the UCLA marching bank or the Bagpipers for a Scottish wedding. Some of these ideas are very pricey but maybe you're a dot.com'er who has lots of do-re-mi. The stripper is always fun for the bachelor party and of course that works both ways, depends on whether you're the bride or the groom. You might want to have a wedding singer or you yourself might want to sing "your" song to your bride. That one is always a realy tear jerker. It is always fun to take dancing classes before the big event so that your first dance can be a tango or a salsa. In any event, you will thrill your guests with your new found talents. At the actual wedding a harpist is very romantic as well as a solo guitarist.....get creative and do what works for your personalities.
