The Complete BBC Sessions is a series compiled in 2004 by the bootleg label Purple Chick and features almost every performance by The Beatles originally broadcasted on various BBC Light Programme radio shows from 1963 through 1965. The series, available as a 10 CDs set, includes all of the 34 songs which had never been officially released previously by the band. Although the songs were recorded ahead of broadcast, allowing for retakes and occasional overdubbing, they are essentially "live in studio" performances. Most of the rare songs are cover versions of material from the late 1950s and early 1960s, reflecting the stage set they developed before Beatlemania. Before this release (originally by Great Dane in 1994, though not so complete and slightly worse in audio quality), comprehensive collections of the Beatles' BBC performances had become available on several different bootlegs with irregular audio quality.
