They went on to sign to 679 Recordings. After 2005 saw a number of singles and their TV debut on MTV Two's Spanking New Music Week. The start of 2006 saw the band gain their highest charting single with "The Boy Who Ran Away", play the ShockWaves NME Awards Tour and make their first appearance on Top of the Pops. The band's debut UK album, Making Dens, was released on 6 March 2006. On 18 September 2006, the band put on a tribute show to Syd Barrett, one of their biggest influences. The show was put on at the Union Chapel in Islington, London. Performers were Kid Harpoon, Lupen Crook, Kate Nash, Dan Treacy and the Television Personalities, Drew from Babyshambles, Ben from SixToes, Lucas from the Cazals and Mystery Jets. The groups created a special fanzine made for the show with entries from all the performers and artwork by the bands. December 2006 saw the band release "Umbrellahead / Half In Love With Elizabeth" through its MySpace site to competition winners. The two tracks were produced by Erol Alkan and were meant to be part of a ten-inch vinyl acoustic EP, but that idea was scrapped. Throughout 2007 the band wrote new songs (including "Hand Me Down", "Pink Elephant" and "Undercover Lover", the latter two being renamed "Veiled In Grey" and "Hideaway" and all three being included on their album Twenty One) and played more gigs around the world, especially in America where they released their debut album Zootime (a collection of tracks from Making Dens, as well as EPs and singles) on 8 May, through Dim Mak Records. Henry Harrison decided to stop playing live with the band shortly afterwards, but is still very much involved and went into the studio with the rest of the band. He still helps with songwriting and occasionally makes onstage appearances. Henry has said, "I'm just another member, I'm one of five. I love it. That whole authority thing served a purpose and when it was done I was glad to relinquish it, because it got in the way of us working properly together." Twenty One (2007–2008) At the end of 2007, the band went on a short club show across the UK, and released a free Christmas single, "Flakes". Their second album, Twenty One, was released on 24 March 2008. Produced by Erol Alkan and mixed by renowned producer Nick Launay,
