Stephen Thomas Erlewine compared them "to a sprightly variation" of the instrumentals from the second side of Low (1977) by David Bowie, albeit with a warmer, less menacing sound. Lead single "Coming Up" – an uplifting dance number – appeared that April with a video (Paul playing all the bandmates, dubbed 'The Plastic Macs', except for the backing singers played by Linda) and with two B-sides by Wings: "Coming Up (Live at Glasgow)", recorded during Wings' December 1979 show there, and the piano laden instrumental "Lunch Box/Odd Sox" (a Venus and Mars outtake). An immediate UK No. 2 hit, "Coming Up" was flipped over for the live Wings version in the US where it became another No. 1 for McCartney, greatly raising hopes for his first solo album proper in years.

"Temporary Secretary" was released as a 12" single in Britain, backed with the experimental non-album track "Secret Friend". Author Howard Sounes thought it a "sexy" track. The single was only released in a quantity of 25,000 copies, failing to make an impact on the charts. The single artwork was created by Jeff Cummins of Hipgnosis. The song was performed live for the first time at the London O2 Arena on 23 May 2015. It was sampled in the 3D RDN remix of "Deep Deep Feeling" on McCartney III Imagined.

EMI reported that the album was on track to equal the sales of Band on the Run. The second single from the album, "Waterfalls", peaked at number nine in the singles chart. In the US, initial sales were strong thanks to the hit single "Coming Up" and the album reached number three in its second week on the Billboard album chart where it remained for five weeks. "Waterfalls" went virtually unnoticed in the US, only "bubbling under" the Billboard Hot 100 at number
