RICHARD: Let’s get this show on the road.
Let’s get this show on the road, an American idiom meaning “let’s get started, let’s get going”. It’s from show business, especially travelling theatre companies, vaudeville troupes, and circuses. It dates to around 1910, but the first citation of it is in the 1951 novel From Here to Eternity, by James Jones.
