Paul McCartney was pictured in Central London on Tuesday.
Meanwhile, earlier this month, it was reported that Paul has donated a set of limited edition photographs by his late wife Linda to Glasgow Museums.
The set of 14 photographs includes images of Sir Mick Jagger and Brian Jones from her first professional photoshoot, as well as family portraits.
The Linda McCartney Retrospective – curated by Paul with daughters Mary and Stella – is currently on show for the first time in the UK at Kelvingrove Art Gallery and Museum.
Deputy leader of Glasgow City Council and chair of Glasgow Life David McDonald said: “The Linda McCartney Retrospective at Kelvingrove Art Gallery and Museum has been very warmly received.
‘We were delighted to be the first venue in the UK to show this exhibition and our greatest thanks go to Sir Paul McCartney for his incredibly generous gift.This wonderful addition to our collection ensures visitors to Glasgow Museums can continue to engage with and enjoy Linda McCartney’s stunning work for generations to come.’
