As a reaction to critics who believed Wings was merely a vehicle for Paul McCartney, the album featured every member of the band taking lead vocals on at least one song, and two songs from the album are written or co-written by band members other than the McCartneys.

McCartney had previously attempted to create a democratic album in Red Rose Speedway, though it would be rejected by his record label.

During the playback of "Must Do Something About It", Paul heard drummer Joe English sing the song and decided to have him take the lead vocal.

The introduction, "Let 'Em In" was perceived as an invitation to join the McCartneys on this fantasy day, with explanation of their philosophy ("Silly Love Songs"), a lunch break ("Cook of the House"), and a chance to get to know McCartney's friends (Denny Laine in "The Note You Never Wrote", Jimmy McCulloch in "Wino Junko", etc.).

[16] In 1993, Wings at the Speed of Sound was remastered and reissued on compact disc as part of The Paul McCartney Collection series; "Walking in the Park with Eloise", which had been released under the name the Country Hams, its B-side "Bridge on the River Suite", and the Wings track "Sally G" (the B-side to their single "Junior's Farm") were added as bonus tracks.

On 23 September 2014 the album was re-issued by Hear Music/Concord Music Group as part of the fifth set of releases, alongside Venus and Mars, in the Paul McCartney Archive Collection.
