The Who performed on The Tonight Show Starring Jimmy Fallon last night to promote their The Who Hits 50! Anniversary Tour, which marks their first appearance on American late-night TV since their 2006 Letterman performance (and their first full-band performance since their appearance in 1967 on The Smothers Brothers Comedy Hour). The band played the full seven minutes of their classic “Who Are You.” Watch here. Watch their last full-band explosive performance from The Smothers Brothers Comedy Hour below.
