After the release of what turned out to be Wings ' final album , '' Back to the Egg '' , McCartney went north to his farm in Scotland to begin some private recordings in July 1979 . " Check My Machine " samples dialogue from the 1957 Tweety and Sylvester cartoon '' Tweet Zoo '' . By sessions ' end , he had recorded over 20 songs . With no immediate use for the recordings , he put them aside for the time being and returned to work with Wings to prepare for a UK tour that November and December . Simultaneously with the performances ( which included the new " Coming Up " ) , McCartney released his first solo single since 1971 , the Christmas-themed " Wonderful Christmastime " , backed with " Rudolph the Red-Nosed Reggae " , which charted at No. 6 in the UK but only No. 83 in the US . The A-side was recorded during the '' McCartney II '' sessions , while its flip side had been cut in 1975 . However , upcoming events were about to change McCartney 's plans with Wings
