John French, AKA "Drumbo", was one of the early Magic Band members, and was in the Magic Band for quite a long time, with his main instrument being the drums.
John French said this recently:
"Although, by sheer coincidence, Zoot Horn Rollo was originally my stage name. I was christened that in late 1967 and then after Bill [Harkleroad] joined the band, Don came up with the name Drumbo for me, and Zoot went to him. It never felt right on me anyway. I believe Alex actually made up the name Zoot Horn Rollo as a joke one day."
