Despite "Give My Regards to Broad Street" being unsuccessful in the box office financially and critically, its soundtrack album sold well.  The title is a take on George M.

Waterfalls (Paul McCartney song): "Waterfalls" is a Paul McCartney ballad from his first solo album after Wings, "McCartney II".  The song has a stripped-down sound, with McCartney only playing a Fender Rhodes electric piano and a synthesizer and singing, and a short solo most likely played on an acoustic guitar.  It was released as a single with "Check My Machine" as its B-Side and reached chart position #9 in the UK.  In the US, however, it was his first single ever to miss the "Billboard" Hot 100 chart, only reaching number 106 despite being the follow-up to the number one hit "Coming Up".  In 2013, "Rolling Stone" rated it the #25 all-time Paul McCartney post-Beatles song, describing how it contrasted with Wings' prior single.

She's My Baby (Wings song): "She's My Baby" is a song credited to Paul and Linda McCartney that was first released by Wings on their 1976 album "Wings at the Speed of Sound".  It is a love song sung by Paul directed at Linda.  Critical opinion of the song has ranged from a description as Paul McCartney's "sweetest, daftest love song" to a suggestion that it deserves an "honor for sheer awfulness."  In 1998, after Linda's death, Paul McCartney rearranged the song for string quartet to be played at memorial concerts for his late wife.  This version was included on the 1999 album "Working Classical".
