Their first album, Room on the 3rd Floor, also hit number one in the UK Albums Chart and would earn Mc Fly a Guinness World Record for being the youngest band to have a debut album enter the charts in the top position, previously held by the Beatles.
That year, Mc Fly would support Busted on tour before going on to headline a personal tour in September 2004.
The band’s second studio album, Wonderland, was released in 2005 followed by Motion in the Ocean in 2006.
