Released on the Beatles' *Anthology 2*, '12-Bar Original' stands as a rare studio recording featuring the band's full lineup, including Ringo Starr on drums. Unlike many of their earlier works, this track was recorded in 1995 rather than during their active years, yet it retains the group's signature harmonies and rhythmic precision. The song's title references the standard twelve-bar blues progression, a foundational element in rock and roll that the Beatles frequently adapted for their own compositions. While not a hit in its original release, the track serves as a valuable archival document of the band's late-career studio capabilities and their continued engagement with classic musical structures.
