John...here's one I wrote that you might want to try.

At the end of the HP....stop the music....and when it becomes silent...go out on the floor with the group and sing (to the melody line)....

You put your money in, but you don't take it out
'cause I come along and I sweep it all about
I do the Hocus Pocus and I make it disappear
And that's the only reason I'm here!
