Paul Williams, already a famous songwriter but before his three great film scores—Phantom of the Paradise, Bugsy Malone, and The Muppet Movie—is one of the best aspects of the otherwise worst of the original “Apes” series, 1973’s Battle for the Planet of the Apes. Williams has the right stature, carriage, and voice to convincingly play the orangutang character Virgil. Cementing everything I’ve heard about Williams—that he’s a totally cool guy—he wanders onto Carson’s stage in full Virgil make-up and croons “Here’s That Rainy Day.” I can’t express to you how much this makes me smile.
By the way, when this was first broadcast, I was less than three weeks old. My mom probably caught it on the TV when she was trying to get me to go to sleep.
