a release to coincide with the airing of the long-delayed Wings Over the World special. While noting that McCartney and Laine's relationship was beginning to unravel at this point, Sounes compares the freshness of these new recordings with the drawn-out sessions for Back to the Egg and writes that the album "was now so overworked it might more aptly have been titled Over-Egged". Impatient at the amount of time being spent in the recording studio, Laine publicly admitted that he was "desperate" to go out on tour. Final overdubbing and mixing In March, Wings moved back to Abbey Road Studios to complete the album. Vocal overdubs were then added to "Winter Rose/Love Awake" and an orchestral-sounding mellotron part to the end of "Getting Closer". Having worked with the Black Dyke Mills Band in the 1960s, when he produced their 1968 single "Thingumybob" for Apple Records, McCartney invited the band down from Yorkshire to overdub brass accompaniment on "Winter Rose/Love Awake". While mixing the album during March, Wings finally discarded the song "Cage", which had been sequenced as the second track, following "Reception". The same alternative running order paired the Rockestra recordings at the end of side two, so that the album closed with the "We're Open Tonight" coda. Holly later recalled that whereas beforehand the band had been confident that Back to the Egg would be a strong album, during the final mixing process "[it] dawned on us there might be problems". At the last minute, "Baby's Request" replaced "Cage" and the running order was revised, with the result that the working-band concept became less pronounced. Artwork and promotional videos The design for the album's artwork was by Hipgnosis, the company responsible for previous Wings album covers such as Venus and Mars (1975) and the recent Wings Greatest compilation (1978). The front cover depicts the five members of Wings in a room, looking down through space at Planet Earth through an open hatchway in the floor; the statuette above the mantlepiece behind them is the same that appears in the Wings Greatest artwork. The picture was taken by photographer John Shaw at his London studio. Photos of the individual band members appeared on the back cover, credited to Linda and Paul McCartney. Working with film company Keef & Co., Wings filmed seven promotional videos for the album, which would later be compiled into the Back to the Egg TV special.
