I usually start the 1st set with Bandstand Boogie. An upbeat tune that the crowd grew up with watching American Bandstand.
This gives the female vocalist a chance to walk around and check the sound levels and give me feedback on the sound level.
I may do a couple of instrumentals to warm up, and get the dancing started.
I then bring up the female singer for introductions and our theme song "Just the Two of Us" which is also the name of our duo.
