Death Cab For Cutie frontman Ben Gibbard has called Teenage Fanclub his favorite band, and a couple of years ago, he released a full-length cover of their 1991 power-pop classic Bandwagonesque. Teenage Fanclub played a show in Gibbard’s hometown of Seattle last night, and Gibbard joined them onstage to play “The Concept,” sharing lead vocal duties with the band’s own Norman Blake.
