Upside Down Singers
The singers are on stage. An announcer explains that they are going to sing upside down! They duck out of sight behind a curtain (a sheet held by two accomplices will do). Placing their hands in their shoes, they wobble the shoes above the curtain top looking as they are having trouble standing on their heads and are about to topple over while singing. They requires practice and the assistance of someone to direct them. To end the skit let one of the curtain holders become distracted and accidentally drop the curtain revealing the "upside down singers" in action.
