Backwards Traveller/Cuff Link: "Backwards Traveller"/"Cuff Link" is a medley of two short songs written by Paul McCartney that was first released on Wings' 1978 album "London Town".  The medley was also released as the B-side of Wings' No. 1 single "With a Little Luck".  Both "Backwards Traveller" and "Cuff Link" were recorded in October 1977 and completed in January 1978.  By this point in the "London Town" recording sessions, guitarist Jimmy McCulloch and drummer Joe English had left the band, so the songs were recorded by only McCartney, Linda McCartney and Denny Laine.

McCartney II: McCartney II is the second completely solo studio album by Paul McCartney, and the first since the formation of Wings in 1971.  It was released in 1980, a year before the band's dissolution and while their future lay in limbo.  The album is a significant departure for McCartney, as much of it relies heavily on synthesizers and studio experimentation.  It was reissued on 13 June 2011 as part of the "Paul McCartney Archive Collection".  The album remains a cult favourite.

I'm Carrying: "I'm Carrying" is a song written by Paul McCartney that was first released on Wings 1978 album "London Town".  It was also released as the B-side of the "London Town" single.  In 2003 it was later released on the soundtrack to the film "The In-Laws".

It was McCartney's first album released after the dissolution of Wings in April, 1981 and McCartney's first album after the murder of former songwriting partner John Lennon.

The Paul McCartney Collection: The Paul McCartney Collection is a series of 16 remastered CDs by Paul McCartney of his solo and Wings albums, with most adding bonus tracks.  The albums in the collection were released separately, with the first eight released on 7 June 1993, and the remainder on 9 August of the same year.  The first half comprised albums from "McCartney" (1970) to "London Town" (1978), and the second half "Wings Greatest" (1978) to "Flowers in the Dirt" (1989).

Girlfriend (Paul McCartney song): "Girlfriend" is a song written by Paul McCartney.  McCartney thought of the song as one that Michael Jackson might like to record, and mentioned this to Jackson at a party in Hollywood.  Jackson had stated in interviews with the music press in the 1970s that he was a fan of The Beatles and the chance to record a McCartney original helped to inspire his next project.  However, McCartney ended up recording it himself with his band Wings, and it was issued in 1978 on the album "London Town".  Subsequently, it was suggested by Quincy Jones as a possible track for Jackson to record for his 1979 album "Off the Wall".  Jones was unaware that the song had been written for Jackson in the first place.  Jackson's recording omitted the middle eight heard in McCartney's version.  It was issued exclusively in the UK in 1980, as the fifth and final single from the "Off the Wall" album.  This proved to be another hit single for Jackson and one of his first recordings of a Paul McCartney song.

Deliver Your Children: "Deliver Your Children" is a song written by Denny Laine and Paul McCartney that was first issued on Wings' 1978 album "London Town".  It was also released as the B-side of Wings' single "I've Had Enough."  In the Netherlands, it received enough airplay to be ranked on the national charts along with its A-side, and joint single reached #13.  On some charts within the Netherlands "Deliver Your Children" was ranked alone on the single charts, and it reached #9 on the Stichting Nederlandse Top 40 chart.  Laine also released solo recordings of the song.

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.
