[6] Rowntree and fellow band member Alex James became involved after taking a behind the scenes tour at Houston's NASA space centre.It carried a signature tune written by Blur to be beamed back from Mars to announce the lander's arrival and one of Hirst's trademark spot paintings to be used for the calibration of Beagle 2's cameras.The Beagle 2 lost contact with earth but was spotted on Mars' surface ten years later by the UK Space Agency in images taken by a NASA orbiter.On his first show he played songs by John Lennon, Elbow and The Polyphonic Spree, interspersed with discussions with his studio friend, "researcher George", on "nerdy" topics like Mars.[11] In a statement, Rowntree said, "As a kid I used to spend hours spinning the dial on my radio, dreaming of escape to all the places whose exotic stations I heard.I've tried to make an album like that – tuning through the spectrum, stopping at each song telling a story about a turning point in my life, then spinning the dial and moving on.He also directed two series of the South Park-esque animated show Empire Square, which made its TV debut on Channel 4 on 18 February 2005.In 2011, he sought selection as the Labour candidate for Norwich South, but lost to Clive Lewis, a journalist and former soldier, who went on to be elected as the constituency's MP.[25] He stood down before the 2021 election, due to the COVID-19 pandemic: in a statement on his website, he said "It has been a joy and a privilege to represent the residents in University Ward, and I've made friendships here that will last a lifetime.In August 2014, Rowntree was one of 200 public figures who were signatories to a letter to The Guardian opposing Scottish independence in the run-up to September's referendum on that issue.[32] In May 2016, he organised a celebrity "Star Boot Sale" to raise funds for mobile health clinics to help Syrian refugees and host Jordanians in need.Stars manning the stalls included Hot Chip, Melanie C, KT Tunstall and Badly Drawn Boy, with Phil Daniels as auctioneer for special lots, like Kylie Minogue's handbag."[40] Rowntree is a trustee on the board of Release, a charity that campaigns for evidence-based drug policies founded on principles of public health.
