More recently, in April 2009, Guest, McKean and Shearer embarked upon the "Unwigged & Unplugged" tour to mark the 25th anniversary of the release of the film "This is Spinal Tap". This time, they appeared as themselves, performing songs associated with Spinal Tap, the Folksmen and various other film and comedy projects from their long careers. After touring thirty cities in the United States, the trio performed a special "One Night Only World Tour" concert at London's Wembley Arena on June 30, 2009, in which they performed (this time in full costume) as both Spinal Tap and the Folksmen.
