And to make it a bit special for his fellow Scousers, they have included a section of never before seen pictures Linda took in Merseyside, on visits to see Paul’s dad Jim McCartney and brother Mike. A contact sheet of pictures she took in Wirral is one of two taken out of the archive for the Liverpool show – the other is a series of Frank Zappa.

But in the end the lens always returns to Paul. From a selfie of the couple in a mirror – Paul cheekily posing with a camera – to him snuggling baby Mary inside his sheepskin coat, each image evokes the huge sense of fun and mutual respect that drove their relationship.

Linda McCartney Retrospective is at the Walker Art Gallery from Saturday until November 1, 2020. Tickets, priced £9 adults with concessions available, must be prebooked here.
