Jimmy Fallon & Fred Armisen Improvise Band Name & Song On ‘Tonight Show’

Fred Armisen swung by his old haunting grounds of 30 Rock to hang with his Saturday Night Live buddy Jimmy Fallon on The Tonight Show. The SNL castmates showed off their improvisation skills by coming up with a band name and song on the fly during a segment called “Build A Band.”

Both Fallon and Armisen are musicians. Some of the highlights of The Tonight Show are Fallon’s musical parodies and Class Room Instruments segments. Armisen utilizes his musical skills in his many projects and often sits in as a guest drummer for fellow SNL castmate Seth Meyers on NBC’s Late Night.
