The single represented both a successful response by Wilson to the British Invasion, and the launch of an unofficial rivalry between him and the Beatles. Released on July 13, All Summer Long debuted on the U.S. Billboard charts on August 1 and remained there for 49 weeks, peaking at number 4 on August 22.
