As a young man, Alex Edward Plasschaert danced professionally with Gene Kelly, Ginger Rogers and Debbie Reynolds.

He was a musical chimney sweep in "Mary Poppins" with Julie Andrews and a rhythmic waiter in "Hello, Dolly!" with Barbra Streisand. He was a choreographer on "Rowan & Martin's Laugh-In," and he worked on the stunts in such movies as "Logan's Run" and "The Omega Code."

Coordinating the cast of zanies on the "Laugh-In" set probably was a chore, but could it have been any more difficult than arranging the movements of the 350 performers who may be onstage at any given time during Bellevue Baptist Church's "Singing Christmas Tree" pageant?
