Someday, someone will make The Simpsons' Planet of the Apes musical — but until then, watch as composer/actor Paul Williams serenades the Tonight Show crowd in his full Battle for the Planet of the Apes orangutan suit.

Williams, who played Virgil the mutant human killer in Battle made a special appearance on this 70s show, treating us all to an amazing song. And giving me a new profile picture! Look, singing apes have proven time and time again to be a massive hit. Broadway, take notice!

The closest we'll ever get to the Planet of the Apes musical from The Simpsons

Thanks for the tip Mike!
