For the new album, "Back to the Egg", McCartney decided to collaborate in the studio with producer Chris Thomas, with whom he had begun working on the audio for two films documenting Wings' last world tour: "Wings Over the World", a television documentary, and the cinema release "Rockshow" (1980). Thomas's involvement would mark the first time that Wings had recorded with an outside producer since their 1973 single "Live and Let Die", which George Martin had produced. Due to his recent work 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.
