20 July 2007, Parr and his band opened for Bryan Adams at the Keepmoat Stadium in Parr's home town Doncaster. Twenty years earlier, Parr joined Adams in his home town where they played to 75,000 at the Canadian Exhibition Centre in Vancouver. In June 2008, Parr was a special guest for the U.S. rock band Journey on their UK tour. In May 2011, Parr performed an acoustic set as a special guest of Richard Marx on his UK tour. Parr released a double album titled Letter to America on 1 June 2011, and subsequently toured in America. On 11 October 2011, Parr was a guest on ESPN show, SportsNation, where he sang a special rendition of "St. Elmo's Fire", replacing the words with Denver Broncos quarterback Tim Tebow. A reworking of the song's lyrics, sung by Parr and titled "Tim Tebow's Fire", went viral on YouTube: as of 13 January 2012 it had received over 19,000,000 views. The video was uploaded by Denver Fox Network affiliate, KDVR. Throughout 2012, Parr toured America as ambassador for the USO playing concerts and benefits for American servicemen and women. That same year, he wrote and produced a new studio album The Mission. The funds went to the USO, USA Cares and Military Families charities. Parr's quest is to raise funds and awareness of the welfare of military personnel as they return home from active duty and transition back into civilian life. In 2014, Parr reunited with The Who, Jeff Beck, Mick Hucknall and other rock musicians for Kenney Jones' Rock & Horsepower concert to raise money and awareness for prostate cancer. Back at his studio "Somewhere in Yorkshire" he joined forces with Guns N' Roses producer Mike Clink, who along with Slash and Nikki Sixx, collaborated on the forthcoming Pete Way album. At the O2, Parr joined producer Tony Visconti, Woody Woodmansey (Spiders From Mars), Glenn Gregory (Heaven 17) and many members of the original Bowie band to perform in the "Man Who Sold the World" concert. Parr continued his work with the military playing concerts and fund raisers for Help For Heroes. Christmas 2014 saw the release of "Ring Out The Bells", a charity single produced by David Mackay, which featured Charlie Norman and the children of St Catherine's School along with guest performances by Parr and Meatloaf duetist Lorraine Crosby. The proceeds went to the Great Ormond Street Children's Hospital. 2015
