From the wiki: “‘Baby It’s You’ was written by Burt Bacharach, Luther Dixon (credited as Barney Williams), and Mack David (elder brother of lyricist Hal David). The song was originally titled ‘I’ll Cherish You’, but was re-written at the request of Dixon who produced the track that the Shirelles released as a single in 1961. The group’s vocals were added directly to Bacharach’s demo recording.
“Dixon’s vocal arrangements for the Shirelles’ recording proved influential in subsequent versions, including that of The Beatles who performed ‘Baby It’s You’ as part of their stage act from 1961 until 1963 before recording it on February 11, 1963 for their first album, Please Please Me. Not released as a single in 1963, ‘Baby It’s You’ was re-released as both a CD single and a vinyl single in 1995 in the UK and the US, peaking at #7 in the UK and #67 in the US.
