covered in dismembered dolls and raw meat – that was selected for the cover of the US LP Yesterday and Today. Arrangement and recording "And Your Bird Can Sing" contains an extended harmony-lead guitar melody, played by Harrison and McCartney. The latter recalled that he and Harrison wrote the part during the recording sessions. McCartney also stated that he helped on the lyrics and attributed the song "80–20" to Lennon. The Beatles first recorded the song on 20 April 1966 at EMI Studios (subsequently Abbey Road Studios) in London. The arrangement was markedly similar to the Byrds' sound; it featured lush vocal harmonies and jangle-style guitars, with Harrison playing his Rickenbacker 360/12 electric guitar. While carrying out vocal overdubs on the track, Lennon and McCartney were overcome by hysterical laughter and unable to sing their parts. Later released on the 1996 Anthology 2 outtakes compilation album, the performance includes the pair giggling, uttering spoken asides, and whistling along with the melody. In his liner notes for the album, Beatles historian Mark Lewisohn comments that the tapes do not indicate the source of the laughter. The group re-recorded the song on 26 April. Whereas the first version was in the key of D major, the remake was played in E major, with the guitarists applying capos to allow for the two-semitone adjustment. Rodriguez and music critic Richie Unterberger speculate that the remake was motivated by the Beatles' realisation that the 20 April recording was overly derivative of the Byrds, and that this aspect had possibly come about through a pun on the word "bird". The session began with Lennon's tongue-in-cheek introduction, "Okay, boys – quite brisk, moderato, foxtrot", and the group performing a rhythm track that Lewisohn terms "very heavy", before the mood was lightened in subsequent takes. The twin lead-guitar approach replaced the Rickenbacker jangle from the first version, and the vocal arrangement was pared down to feature mainly Lennon. Harrison and McCartney used their Epiphone Casinos for the lead-guitar lines. In the description of Charles Shaar Murray, the completed track is nevertheless one of the guitar-based songs on Revolver that "glisten" with "cascades of jangle", as the Beatles responded to "what The Byrds had done with the Fabs' own proto-folk-rock sound on A Hard Day's Night". The band used take 10 as their basic track, before overdubs. The latter included McCartney's bass guitar and Ringo Starr adding cymbal and
