"Let's Go Away for Awhile" is an instrumental that features 12 violins, piano, four saxophones, oboe, vibraphones, and a Coca-Cola bottle used as a guitar slide. In 1966, Wilson considered the track to be "the finest piece of art" he had made up to that point, and said that every component of its production "worked perfectly". The piece had the working title "Let's Go Away for Awhile (And Then We'll Have World Peace)", a reference to one of Wilson's favorite comedy recordings, John Brent and Del Close's "How to Speak Hip" (1959).
