For KC of KC and the Sunshine Band (search), falling off the stage during a concert is definitely not the way he likes it. Uh huh, uh huh.

KC, whose real name is Wayne Casey (search), took a headfirst fall off a 6-foot-high stage while performing Saturday at the Cinco de Mayo Festival in Phoenix. The 54-year-old singer suffered a sprained knee and a cut over his right eye that needed six stitches.

The band was two songs into its set when Casey took the tumble, just as "Boogie Shoes" was beginning.

"I left my shoes at the hotel and had to perform in a new pair," Casey, who is recovering at his Miami home, said in a statement Monday. "I picked the wrong pair of Boogie Shoes!"

Casey nevertheless resumed his performance and went to a local hospital afterward.

KC and the Sunshine Band's `70s disco hits include "(That's the Way) I Like It," "Get Down Tonight" and "(Shake, Shake, Shake) Shake Your Booty."

They will continue with shows in Winter Haven, Fla., on Friday and in Atlanta on Saturday.
