ah yes - a take on the Aprils Fools day gig the Grateful Dead did as a prank in 1980 - Capitol Tht - Passaic, NJ. - they all came out playing different instruments on Promised Land: Bobby on keyboards, Brent &amp; Jerry on drums, Billy on bass - Mickey on rhythm guitar and vocals, and Phil on lead guitar.
funny part - they pulled it off, altho not very well.
would be fun to see GPN do it at a show -(hint hint)
