His love songs have inspired millions, but over the weekend Sir Paul McCartney had a more direct role in the love story of one Canadian couple.
The former Beatle was in Winnipeg, Manitoba, for a concert when he photo-bombed a couple taking pictures before their wedding.
McCartney passed the couple while riding his bike along the river during his downtime on Saturday.
But when McCartney and his two bodyguards hit a dead end, they had to turn around and ride past the couple again.
"It was very brief, he shook our hands, said congratulations took a couple quick photos and then they were off," he told the CBC.
The couple said they are fans but hardly Beatle-maniacs, and have kept a healthy perspective on their brush with mega-stardom.
"This is was a nice thing on a day filled with wonderful events," Mr Gregg said.
