Gary go to any casino club and watch the bands play dance music...45/15 baby non stop.....Once you get the set medleys in your head it's pretty easy to knock em out..
the trick is "the lead in intro chain-link" to each song makes it flow one into the other all thru the set. When I was musical director on the 50's Oldie tour back in the 80's with a 9pc show band we did 2 shows like that every night on land & sea.
Works out good as long as everyone is in Sync.
