What is Mr A-Z?
Mraz began a long-running tour in support of Mr.
A-Z at the San Diego Music Awards on September 12, 2005.
Why is this significant?
The tour featured several opening acts, including Bushwalla and Tristan Prettyman, with whom he had written the duet "Shy That Way" in 2002.

Question: Where was the tour?
