Back to the Egg is the seventh and final studio album by Wings, released in 1979. It is also Wings' first album for Columbia Records after leaving long-time United States distributor Capitol Records in 1978. When McCartney returned to international distribution by EMI in 1985, Back to the Egg and the rest of McCartney's Columbia-era releases moved to Capitol/EMI in the US. By the end of June 1978, this last incarnation of Wings settled into Spirit of Ranachan Studios on McCartney's farm in Scotland, then moved onto Lympne Castle near Hythe in Kent (not far from McCartney's new home in Peasmarsh, near Rye, Sussex) in September and Abbey Road Studios in October, where McCartney organised a special one-off session. On 3 October, Wings recorded two tracks, "Rockestra Theme" and "So Glad To See You Here" with many celebrity guests under the heading of Rockestra. James Honeyman-Scott of the Pretenders, Hank Marvin of The Shadows, The Who's Pete Townshend, Pink Floyd's David Gilmour, Led Zeppelin's John Paul Jones, John Bonham and The Attractions's Bruce Thomas all took part. On 10 October, versions of "Getting Closer", and "Baby's Request" were recorded at Abbey Road Studios. Overdubs for the two tracks were laid down in November, at Replica Studios, located in MPL Communications' London offices. Sessions were paused, and continued in January 1979.
