Chances are if you're having a marquee you'll need some form of entertainment such as a DJ or band. If so, you should check these guys out: The Jackson 3. We get asked to recommend bands a lot and I'm quite particular about music (music graduate and former function band player myself blah, blah, blah; brag, brag, brag) and these guys are the cat's pyjamas. I heard them at the Milton Abbey School Leavers' Ball at the weekend where they laid down a seriously funky groove (they also played in a wedding marquee of ours the weekend before and got rave reviews). Book soon to avoid massive disappointment!
