Recording for the album began in June 1978 and lasted for almost a year. The sessions took place at Spirit of Ranachan Studios in Scotland, Lympne Castle in Kent, London's Abbey Road Studios, and Replica Studio – the last of which McCartney built as an exact replica of Abbey Road's Studio Two when the latter became unavailable. Wings returned to Abbey Road in March 1979 to complete the album, before filming a series of promotional videos in Lympne and elsewhere, for what became the "Back to the Egg" TV special.
