"Step Inside Love" was written by Paul McCartney for Cilla Black to use as the theme song for her TV series, Cilla, in early 1968. The two made a demo together, with McCartney playing a solo acoustic guitar and Black singing (and responding to commentary by the songwriter).
Black's official version was released on 8 March 1968.
A version of the song was released on The Beatles Anthology 3 (Disc 2, track 23), a recording made at EMI Studios on 16 September 1968 (so well after Black's recording) that features Paul's vocals and a distinctly latin-flavored beat. It is also followed by a Lennon comment about "Los Paranoias", on which Paul then improvises. The phrase "los paranoias" would be used in "Sun King" off Abbey Road.
This blog is a workshop for developing my analyses of The Beatles' music.
