Just Google “Rat Pack revue” and you’ll get plenty of results; every two-bit talent booker in the country seems to have a stable full of Franks and Deanos and Sammys.
“Sandy Hackett’s Rat Pack Show,” coming to the 4th Street Theatre next week, is different for two reasons. First: It is not just a revue; it’s a musical with a narrative. Second: Its star actually grew up around Frank Sinatra, Dean Martin, Sammy Davis Jr. and Joey Bishop. Hackett is the son of comedian Buddy Hackett, who was close with Bishop and ran in the same Vegas and Hollywood circles as the other three.
What that means in terms of the product on stage is difficult to say. But, if you were the sort of person inclined to buy a ticket to a show full of entertainers pretending to be other entertainers, wouldn’t you want the one who had a guy who actually knew those other guys?
