Rat Pack was an American pop and easy listening band that was formed in 1960 by an American actor Humphrey Bogart. The name "Rat Pack" was first used to refer to a group of friends in Hollywood, including the young Frank Sinatra. The name may also refer to the belief that an established pack of rats will belligerently reject an outsider who tries to join them ("Never rat on a rat"). According to Stephen Bogart, the original members of the Holmby Hills Rat Pack were Sinatra (pack master), Garland (first vice-president), Bacall (den mother), Sid Luft (cage master), Bogart (rat in charge of public relations), Swifty Lazar (recording secretary and treasurer), Nathaniel Benchley (historian), David Niven, Katharine Hepburn, Spencer Tracy, George Cukor, Cary Grant, Rex Harrison, and Jimmy Van Heusen.
