In February 2023, David Paton, guitar case in hand, strode across the most famous pedestrian walkway in rock history and into London’s Abbey Road Studios.

Paton was no stranger to the rooms where the Beatles changed the course of popular music: His 1970s pop-rock band Pilot recorded two albums there. In his second life, as an in-demand studio and touring musician for the likes of Kate Bush and Elton John, he clocked numerous sessions with the prog-rock outfit the Alan Parsons Project, whose namesake produced Pilot’s signature hit, “Magic.” He even spent some time there with his boyhood hero, Paul McCartney, singing backup vocals on Wings’ “Mull of Kintyre.”
