The Birthday Party was the first album by The Idle Race, a psychedelic pop band, released in 1968 (see 1968 in music). This quasi-concept album was the first to be composed almost entirely of songs by a young Birmingham guitarist/singer named Jeff Lynne. The LP came in a gatefold sleeve, the first of its kind since the Beatles' Sgt Pepper and the Rolling Stones' Their Satanic Majesties Request albums. The inside sleeve art included a mock birthday feast attended by many British Celebrities, including most of the Radio 1 disc jockeys, the Beatles, the Duke of Windsor, actor Warren Mitchell in his role as Alf Garnett, and group leader Jeff Lynne as an eight-year-old schoolboy. In the U.S. the cover art was different with a rather psychedelic-styled paisley pattern behind the band.
