As a chart-topping band, they're more used to performing in front of crowds at Wembley Arena and Party in the Park.
But now McFly can add a primary school in suburban Leeds to their list of gigs after playing at a packed-out school assembly
The foursome – Harry Judd, Danny Jones, Dougie Poynter and Tom Fletcher – performed three songs to pupils at Cottingley Primary School after pupil Ami Thorpe, 11, won a competition with 96.3 Radio Aire
More than 100 youngsters screamed as the group walked onto the tiny stage in the school hall, where they opened with latest single Party Girl.
They went on to perform old favourite All About You, closing with their debut hit Five Colours in Her Hair.
In a chat with the YEP, Danny said: "It's good playing for the younger fans because they're not as judgmental as older audiences.
"They're a bit more understanding. If they're really young, they just stand up and dance around."
Tom added: "Adults are quite hard to impress but the young fans are always very sweet."
The guys also answered questions on stage from the youngsters, put to them by Radio Aire's breakfast show hosts JK and Joel.
It emerged that Tom's favourite food is pizza, Danny's favourite karaoke song is My Heart Will Go On, Harry was "mischievous" in school and Dougie thinks dating Frankie Sandford, a member of girl band The Saturdays, is "awesome".
The boys, who have a new album called Above the Noise out next month, said performing at schools like Cottingley was a "lot of fun".
Dougie told the YEP: "It's just nice to come and entertain people for the day. When this sort of thing happens in school, it's always really exciting for the kids. It's something a bit different."
Tom added: "Although we never had anything like this at our school. But firemen came in to do assemblies and that was exciting."
They also said they were enjoying the latest series of X Factor and tipped either Cher Lloyd, Matt Cardle or Nicolo Festa to win.
Harry said: "Cher is getting a lot of stick and I don't know why, it's really annoying me. People are having a go at her for mucking up her audition but she had a reason to sing badly – she was ill. Katie didn't have a reason."
Danny added: "Cher is just like Cheryl though. They have the same dress sense, the same tattoo and even half of the same name."
Ami, who presented the boys with a teddy bear and a thank you cookie after the gig, said: "It was everything I hoped it would be. They were lovely and it's been a brilliant day."
