Mraz's 2008 world tour took him all over the United States, Europe, Asia and Australia. His personal photo travelogue from the world tour was published as a book, titled "A Thousand Things" (2008). The book contains Polaroids from his time touring and backpacking around Europe, and was launched with a photo exhibition at Charles Cowles Gallery in New York City at the end of 2008. Also in 2008, Mraz played with Eric Clapton to a crowd of 45,000 in Hyde Park, London, sold out London's Royal Albert Hall and performed at the Nobel Peace Prize Concert in Oslo. That year also marked his Music, Magic & Make Peace Tour with Bushwalla, The Makepeace Brothers, and magician Justin Willman. Mraz brought along the magician after picking up magic as a hobby during recording sessions for "We Sing. We Dance. We Steal Things." On January 31, 2009, Mraz was the musical guest on "Saturday Night Live", performing "I'm Yours" and "Lucky", which peaked on the Hot 100 at number 82.
