Young Frankenstein who, as Elizabeth did when abducted by the monster, sings the refrain "Ah, Sweet Mystery of Life". After several box office failures (which included now-cult classics "The Producers" and "Willy Wonka & the Chocolate Factory"), Gene Wilder finally hit box office success with a pivotal role in the 1972 Woody Allen film "Everything You Always Wanted to Know About Sex* (*But Were Afraid to Ask)". It was around that time that Wilder began toying around with an idea for an original story involving the grandson of Victor Frankenstein inheriting his grandfather's mansion and his research. Wilder had played around with

They were not looked after which was sad." Following its lack of success, "Know Who You Are" was quickly deleted by Polydor and has since become a collector's item. The "Rare Record Price Guide" of 2014 valued the single at £80. The song later received greater recognition when a live version was included on "Slade Alive!", which became the band's first hit album when released in 1972.
