I wish I lived in the Golden Age, giving it up on the Broadway stage. Hang with the rats and smoke cigars, have a break with Frank and count the stars. Dressed to the night, we've had to much. Shiny jewels, casino cash. Tapping feet, wanna take the lead. A trip back in time is all I need
I'm assuming the Frank referred to is Frank Sinatra, so the "rats" would be the members of The Rat Pack.
From Wikipedia: The Rat Pack was a group of actors originally centered on Humphrey Bogart. In the mid-1960s it was the name used by the press and the general public to refer to a later variation of the group, after Bogart's death, that called itself "the summit" or "the clan," featuring Frank Sinatra, Dean Martin, Sammy Davis, Jr., Peter Lawford, and finally, Joey Bishop, who appeared together on stage and in films in the early-1960s, including the movie Ocean's 11. Sinatra, Martin and Davis were regarded as the group's lead members. (Source)
