I think "Oyee Oyee O is the local translation of the jungle calls Tarzan makes when he need to summon the assistance of his animal friends (Chita, the elephant, Simba the Lion, and I think a chimp named ??? can't remember), the series was shown on Channel 5 every Saturday afternoon and was a regular family event to gather in front of our Black& White TV and eat chestnuts. There was no goddamned person who invented the Singlsih nursery rhyme, but many people just "aped" Tarzan's call, and being SIngaporeans, this was how it turned out. If this causes goosebumps on you, wait till you hear some kid yell "Birrrrdman, and runs down the street screeching like a hawk!"
Also, if you have watched any Tarzan movies (TV or big screen) - have you ever wondered why he is always clean shaven?
Cheers!
