"Lazy Sunday" mixes pop with a traditional cockneyEast End of Londonmusic-hall sound. The song was inspired by Marriott's feuds with his neighbours[7] and is also noticeable for its distinct vocal changes. Marriott sings large parts of the song in a greatly exaggerated cockney accent, partly due to an argument he had with the Hollies, who said that Marriott had never sung in his own accent.[8][5] In the final bridge and the last two choruses, he reverts to his usual transatlantic (singing) accent. John Lydon cited the Small Faces as one of his few influences as vocalist for the Sex Pistols, and evidence of Marriott's influence on him can be found in this song.
According to Small Faces keyboardist Ian McLagan, Lane's "rooty dooty di" vocal lines were in imitation of a member of the Who's road crew; the two bands had recently toured Australia together.[9]
"Lazy Sunday" appears as track six on the album Ogdens' Nut Gone Flake, and is the last track on Side A of the vinyl release. Despite its success, the single was released against the band's wishes, and this contributed to Marriott's departure.[10]
The low-budget promotional video for "Lazy Sunday" was filmed at various locations, including Kenney Jones's parents' home on Havering Street in Stepney, east London.[12]
The London-based indie rock/garage revival band The Libertines covered the song in 2003 as part of the soundtrack to British film Blackball. It is also available as part of the Blackball OST album.
