The live Simpsons event took place at the Hollywood Bowl in LA over the weekend, and thankfully there are plenty of clips online for those of us not lucky enough to attend. Above, check out Conan O’Brien’s performance of “The Monorail Song” with the Los Angeles Gay Mens’ Choir – which O’Brien respectfully dedicates to the great Phil Hartman – then click through for a YouTube clip of nearly the entire show, with appearances from Yeardley Smith, Nancy Cartwright, Hank Azaria, Jon Lovitz, Weird Al, and more.
