Hidden Track has the scoop on Trey Anastasio stopping by Conan O’Brien’s Legally Prohibited from Being Funny on Television Tour:

Former 70 Volt Parade front man Trey Anastasio joined fellow redhead Conan O’Brien onstage tonight during the TV host’s show at the Tower Theatre in Upper Darby, PA. Big Red led the Legally Prohibited From Being Funny on Television Tour Band through a take on the Marshall/Anastasio ditty Alaska while wearing a Philadelphia Flyers jersey.

Love the band “woo woo’s” to signify the train whistle; what a treat for the Phish fans in attendance. “Leave that guitar when you go…it’s mine now.” Love it.
