Singer Florence Welch joined fans in singing Happy Birthday to her father as she closed the Apple Music Festival.
Welch also dedicated a song from her album Lungs to her father, Nick Welch.
"Thank you so much for everything, I'm so glad you're here tonight," she said, recalling how before the band made it big he drove them around the UK, Germany and France in his camper van while they toured as a support act.
Welch and her band, Florence + The Machine closed the 10-day music festival in spectacular style.
With her trademark bare feet, she greeted fans at Camden's Roundhouse saying: "Hello everyone! It's so nice, I can see everyone. We are Florence + The Machine, thanks for having us."
Sporting a shimmery two-piece suit she jumped up on the railings at one point, reaching into the crowd to greet her fans.
Fans were not shy to show their love of her, with one throwing a t-shirt on stage for her.
During her hit song, Dog Days Are Over, she encouraged everyone to take off an item of clothing and swing it around their heads.
She came back on for an encore to perform a few more songs, among them new single, What Kind Of Man.
Singer James Bay was due to open for her, but was forced to cancel at the last minute.
Bay revealed he had been hit by a cold, and had to cancel his Apple Music stint and another performance on the same day.
He told fans on Twitter: "And of course this rubbish cold means I won't be able to open up for the amazing Florence + The Machine for the Apple Music festival at the Roundhouse tonight either. Going to get better as fast as possible."
No replacement stepped in to perform in his place, leaving Welch and her band to come on stage at 9pm.
The Apple Music Festival has seen acts like One Direction, Little Mix. Ellie Goulding, Take That and Pharrell Williams perform to fans who were lucky enough to win tickets to see them.
