Oh yes, nobody does the Tarzan call better than JW. (well Carol Burnett does pretty well.)
I always was under the impression that (according to Hollywood legend) the Weissmuller Tarzan yell was created back in 1932 by the Sound Department at MGM studios for
Tarzan the Ape Man, Weissmuller's first Tarzan outing. (And no, I'm not "outing" Tarzan!
) I had heard that the famous cry was a human voice interspersed with a yodel played at high speed, thus producing a sound that was impossible for a human being to perfectly replicate.
However...
An Internet search turned up a lot of contradictory information and conflicting stories (it figures).
Tarzan yell (Wikipedia) And, of course, just like virtually everything else on the 'Net, the Tarzan yell can also be downloaded for use as a cell phone ringtone.
