"There was a lovely song that our kid did, and they had a lovely dance together," Paul's brother, Mike McCartney, told reporters. "That was a nice little highlight of the evening."
The sibling – who served as Paul's best man – spoke outside the house in St. John's Wood where the reception took place, with such guests who include fellow Beatle Ringo Starr, Rolling Stone Ronnie Wood, the bride's second cousin Barbara Walters, and such fixtures from the '60s as model Twiggy and artist Peter Blake.
On his way inside, Starr told PEOPLE that his message to the happy couple was "Peace and love," and said of the bride: "Nancy's a beautiful woman."
Twiggy said: "I'm going to go in and give him a big kiss. … We're just very happy. We love them both to bits."
Pronouncing Nancy "gorgeous," the actress and original iconic waif model said that she was looking forward to the vegetarian banquet. "I'm starving," she said.
Walters told PEOPLE that the wedding "was lovely."
Welcoming Shevell to the McCartney clan, Mike McCartney described the wedding to PEOPLE as, "Fabulous. Beautiful. It was just lovely and peaceful. Smashing lovely feel. I'm happy for my brother, he's a lovely brother."
As for what is special about his new sister-in-law, Mike said: "Nancy is lovely, too. She is a charming lady. … She's one of us now!"
