Pearl Jam rocker Eddie Vedder made a surprise appearance at the Seattle stop of Conan O’Brien‘s Legally Prohibited From Being Funny on Television Tour, to deliver a musical birthday card to the former Tonight Show host as he turned 47 .
Vedder took to the stage and performed a hilarious sing-a-long of John Lennon‘s “Oh Yoko” on a ukulele, replacing the refrain with “Oh CoCo.”
