Harry the Hairy Ape
From the song "Harry the Hairy Ape" by Ray Stevens from his 1963 album, This Is Ray Stevens.
Actual gorilla, who, after escaping from the zoo, tries to scare a passing stranger who turns out to be a local radio DJ:
The DJ played Harry's record (What record?) Shut up!
It was a hit and he became a star.
Got him some tight britches, got him a manager.
Went on a promotion tour, combed his hair back and took up playing the guitar.
And every Sunday afternoon you can go see Harry at the zoo.
And the girls will scream & he'll sit on his swing and pick and sing his hit record for you.
