A Quick One is the second studio album by English rock band The Who, released in 1966. The album was also released under the title Happy Jack on Decca Records in the United States, where the song "Happy Jack" was a top 40 hit.
The Who's second studio album departs from the R&B emphasis of the first. Part of the marketing push for the album was a requirement that each band member should write at least two of the songs on it, though Roger Daltrey only wrote one (See My Way), so this is The Who album least dominated by Pete Townshend's songwriting. It was recorded at IBC Studios, Pye Studios and Regent Sound, in London, England in 1966 with Kit Lambert as the record producer.
"Heat Wave", the only cover-version and the only reversion to the group's soul influences, a song by Tamla'sHolland-Dozier-Holland team, was replaced by "Happy Jack" on the original US release but included on the 1974 double album repackaging of A Quick One and The Who Sell Out.
"Boris the Spider" quickly became Entwistle's most popular song, still performed decades later: in later years he often wore a spider necklace. "Happy Jack", though quirky, remains a favourite.
Keith Moon's "I Need You", was originally titled "I Need You (Like I Need a Hole in the Head)". Moon thought The Beatles spoke in a secret language behind his back, and this song was his way of getting back at them. Although Moon denied that a vocal part in the song was a John Lennon imitation, Entwistle said that, in fact, it was.
"Cobwebs and Strange" was originally called "Showbiz Sonata". Though Entwistle claimed that the melody came from the UK television series Man From Interpol.
The album was intended to be pop music, a sonic participant in the pop art movement. The cover was designed by the pop art exponent Alan Aldridge, with the front cover depicting the band playing their instruments. The back cover of the UK release is black, with the title and track listing across the top, and a colour head-shot photograph of each band member with the letters of "The W H O" superimposed individually over their faces. The back cover of the US release is a black-and-white photo montage of the band members accompanied by a short personality sketch of each (infamous among Who fans for Keith Moon's humorous assertion that he was keen on "breeding chickens"). A track listing, a couple of paragraphs touting the band, an ad for their first album, and a technical blurb are also crowded onto the back cover of the US release.
