McCartney first taped a 45-second portion of a song he wrote in Campbeltown, "The Lovely Linda". As with much of the album, McCartney sang the composition accompanied by acoustic guitar before filling the remaining tracks on the Studer with a second guitar part, bass and percussive accompaniment. Although this performance of "The Lovely Linda" was only intended as a test of the new equipment, it would be included on the official release, as the opening track, complete with the sound of McCartney giggling at the end of the recording. Reflected in the sequencing of the album, the second and third songs McCartney taped were "That Would Be Something", also written in Scotland, and the instrumental "Valentine Day". The latter was one of three selections on "McCartney" that its creator "ad-libbed on the spot", he later claimed, along with the similarly rock-oriented "Momma Miss America" and "Oo You".
