Who's on First? (album)

Who's on First? is a live 2000 vocal album by the songwriters Bob Dorough and Dave Frishberg. It was recorded at the Jazz Bakery in Los Angeles.

Dorough and Frishberg had been friends for several decades prior to this recording and had written the song "I'm Hip" together in 1965. The pair were persuaded to perform as a duo by the owner of the Jazz Bakery club, Ruth Price, and this live album was made of their collaboration. The opening song and title track, "Who's on First?" is about the problem of deciding which of the pair should perform first in the show.

The pair performed using two grand pianos that faced each other on the stage. Each performed four solo songs with the rest recorded in duet.
