Input: Consider Input: Question: Has the Wonder World Tour recording artist ever won a Grammy? Passage:The Wonder World Tour was the second concert tour by American recording artist Miley Cyrus. The tour was held to promote her second studio album Breakout (2008) and first extended play (EP) The Time of Our Lives (2009). It began in September 2009 and concluded in December 29, visiting cities in the United States and United Kingdom; thus, the Wonder World Tour became Cyrus' first world tour. It also became Cyrus' first tour not to incorporate performances as Hannah Montana, although "Let's Get Crazy", an official Hannah-song, was performed. Alternative band Metro Station served as opening act for all tour venues. It was sponsored by Wal-Mart and promoted by AEG Live. All tickets from the Wonder World Tour were sold using paperless ticketing, in order to prevent ticket scalping similar to what had occurred during Cyrus' previous tour. One dollar from each ticket sold was donated to the City of Hope National Medical Center, an organization devoted to the fight against cancer.
