A Quick One

A Quick One is the second studio album by the English rock band the Who, released on 9 December 1966. In the United States, where the song "Happy Jack" was a top 40 hit, the album was released in April 1967 under the title Happy Jack with a slightly altered track listing. Unlike other albums by the Who, on which guitarist Pete Townshend was the primary or sole songwriter, A Quick One features significant songwriting contributions from all band members; lead vocalist Roger Daltrey contributed one song, and bassist John Entwistle and drummer Keith Moon each contributed two. The album also included a cover of the Holland–Dozier–Holland song "Heat Wave" and ends with a musical suite titled "A Quick One, While He's Away", which served as an inspiration for later rock operas for which the Who would become known.
