A much anticipated revival of the Olsen and Johnson musical revue, Hellzapoppin is renowned as the zenith of craziness and chaos on Broadway. Audiences were literally under assault during the original run, the victims of practical jokes, running gags, malfunctions and crazed intruders. Hellzapoppin, for many years the longest-running production in Broadway history, is today remembered as the inspiration for the '60's TV hit Rowan and Martin's Laugh-In, the comedy show Hee-Haw! and Off-Broadway's The Mad Show, which spawned Saturday Night Live.
