This was a yearly event at the Filmore called "Live Nude Bands". The Gun and Doll Show always does it's best to stand out while fitting in.... For some reason we always headlined :)

"This is the kind of showmanship we can applaud. At the third annual Live Nude Bands at the Fillmore West in San Francisco, local Bay Area bands pulled a move for the sake of posterity--and in anticipation of future episodes of Behind the Music--by performing in the nude. Pictured above is the 50 Guitar Orchestra, a rock-and-roll symphony conducted by the Gun and Doll Show. If you look closely enough, you may see one or two vocalists who are not above lip-synching." - Playboy
