not be released until much later in the band's career: "One After 909" (later re-recorded, appearing on Let It Be) and "What Goes On" (later re-recorded, appearing on Rubber Soul, credited as Lennon–McCartney/Starkey to reflect Ringo's contribution to the lyrics). Although both songs were rehearsed, only "One After 909" was recorded, and even then the results were deemed unsatisfactory for release. John Lennon overdubbed the harmonica without the other Beatles eight days later. According to multiple sources, John came to the session directly from bed due to a severe cold. Engineer Geoff Emerick said it took John numerous takes to produce a satisfactory result because he was so unsteady. The stereo mix of the song (included on the Capitol LP The Beatles' Second Album) is noticeably different from the original single mono mix (re-released on CD in 1988 on the compilation Past Masters, Volume One) in the middle 8. In the stereo version, a couple of extra harmonica lines can be heard, as well as at the very end of the song. In addition, this stereo mix contained reverb added by Capitol. The unadulterated stereo mix was released for the first time on the 2009 remastered CD Past Masters. Cover versions The song was covered by the Smithereens on their 2008 album B-Sides The Beatles''.
