The great Noel Coward had to try to one-up Mr. Porter with his celebrity version, probably from the '50s.

A few choice lines:
The Brontes felt that they must do it,
Ernest Hemingway could----just----do it...
E. Allen Poe, ho ho ho, did it, but he did it in verse,
H. Beecher Stowe did it, but she had to rehearse.
In Texas some of the men do it,
Others drill a hole and then do it...
Teenagers squeezed into jeans do it,
Probably we'll live to see machines do it...
Each tiny clam you consume does it,
Even Liberace, we assume, does it...
Let's do it, let's fall in love!
