Jeff and I have booked a band for our reception! We're going to have Synergy - a 10 piece band that plays a very wide range of music - from Frank Sinatra to Black Eyed Peas! My family went to see them perform live and really liked them, and they've won a number of awards - so it should be great!
They'll play over the course of four hours, with three twenty minutes breaks (during which we can put on a CD or iPod).
Check out their website to see samples of their music: http://synergy-dwmusic.com/
