Eddie Vedder and Mike McCready of Pearl Jam joined Conan O’Brien on-stage in Seattle Monday night, April 19th, to help celebrate O’Brien’s 47th birthday, Reuters reports, reprinting an article from Billboard.
O’Brien’s birthday was actually Sunday, April 18.
Vedder sang "Rise," and then John Lennon’s "Oh Yoko," changing the words to "Oh Conan," the article says. Vedder then brought out McCready for a cover of the Who’s "Baba O’Riley."
Pearl Jam was also a guest on the first "Tonight Show" that O’Brien hosted.
