First out of the gate, early 1970s: Don Livingston, Livingston's Gone To Texas, Asco, DL 003, Track A5, Killing Me Softly With Kung Fu. Credit to the originals Fox & Gimbel and David Bradley for the comedy. Available on ytube.

Later release of a live show: The David Bradley Story, Mega Records, 1982, 2xLP, Track B2, Kung Fu. Credit to the originals Fox & Gimbel. Not so easy to find.

“Picture in your mind: Frank Zappa, Lenny Bruce, Mary Poppins, the Wicked Witch of the West, and that covers David Bradley.” [Liner Notes]

PS: Bradley was also in on the so-called 'cosmic cowboy' thing in the one LP band “O.D. Corral.” No idea what he's been up to lately.
