McFly have revealed meeting their fans can make them dizzy.
Tom, Dougie, Harry and Danny were all busy meeting, greeting and signing autographs at Glasgow's Braehead Shopping Centre this week.
Danny said: "It's quite good fun coming to do signings, it's always mad. All of the fans are there screaming and it's a bit weird actually, because you get a bit dizzy because you're like 'hi, hi, hi, how are you today, how are you today, thanks for coming, thanks for coming'.
"So you get a bit dizzy, but you just need a coffee and you'd be laughing."
Danny also revealed the band are returning to Glasgow on tour in November.
McFly previewed their new album Radio:ACTIVE at the Shepherd's Bush Empire in London last week.
The first song of the one-hour set was On The Radio - their forthcoming first single from the album. Much to the amusement of Tom, it was met with delight from the screaming fans. He later asked: "Why do you know the words to these songs? YouTube?!"
The band also thanked members of their new label, Super Records, which they set up after leaving Island Records, and described their "amazing" time in Australia where they recorded their new album.
However they were keen not to leave their previous hits behind, with the fans enjoying Obviously, All About You and the last song of the night, Five Colours In Her Hair.
On The Radio is released on July 14.
