Have you ever been walking around a 99 Cents store and seen a bottle of cheap cologne with a sticker on the box that reads: "If you like "Calvin" you'll love "Kevin!"? Apparently the same sort of thing applied to crooner/goofball double acts in the 1950s. Ladies and gentlemen, meet ersatz Martin and Lewis, Sammy Petrillo and 'Duke' Mitchell. There is not very much information about these guys online, but these four links, to the Wikipedia entries for Sammy Petrillo, Duke Mitchell, an interview with Sammy Petrillo, and an interview with "Bela Lugosi Meets a Brooklyn Gorilla" director Herman Cohen are probably all you'll need. Thanks Tara McGinley!
