British rock legends the Who will be kicking off their 36-date North American tour with a November 1 show at BankAtlantic Center. Though slightly older and with considerably less hair, the band will be playing music from their 1973 double album, Quadrophenia, a psych-rock opera chronicling the life of a schizophrenic English teenager.
It was on this very same tour back in 1973 that the Who experienced one of its strangest onstage moments. A fan from the audience actually filled in for an "incapacitated" band member during a performance. In honor of this unlikely substitution, we've assembled a list of the five greatest fan fill-ins of all time, those rare moments when an audience member goes from being an average chump to a rock god in the blink of an eye.
