As they greeted fans in a city center music store, McFly declared that their most recent album was the "best" they had ever created.
The pop group, who have been together for 20 years, was in Chelmsford, Essex, to celebrate the release of their newest album, Power to Play.
Prior to their UK tour, their seventh album will be released.
It was the "most exciting" album release since their debut, according to Chelmsford native Harry Judd.
The drummer continued, "We really think this is the best music we've ever created, and it's so nice to see the fans' reactions.
Maisie, a McFly fan, traveled to West Sussex's Crawley to meet the band.
She claimed to have been a fan for 20 years and was commemorating the milestone by attending the signing and going to this year's 14th concert.
McFly will perform in August at the Newmarket Racecourse in Suffolk as part of their tour, and in October and November at Norwich.
