for iTunes, with the addition of Wings' 1979 non-album single "Goodnight Tonight", in its extended form. Background After the release of the album London Town (1978), Wings band leader Paul McCartney hired two session musicians, drummer Steve Holley and lead guitarist Laurence Juber, to replace former members Joe English and Jimmy McCulloch. With the new line-up – Wings' sixth since its formation in 1971 – McCartney intended to record a raw rock and roll album and return to touring, for the band's first concerts since their successful Wings Over the World tour of 1975–76.

After working with the Pretenders and the Sex Pistols, Thomas brought a punk rock and new wave influence to Wings' sound, matching McCartney's desire to reflect contemporary musical trends. Songs Although London Town had featured a significant level of contribution from Laine as a songwriter, all but one of the songs on Back to the Egg are credited to McCartney alone. The album was originally planned around a loose conceptual theme, about which authors Chip Madinger and Mark Easter write in their book Eight Arms to Hold You: "The idea was to have a
