Question: What song on Hammer's debut album samples a song by the same name from BB King? Passage:Before Hammer's successful career (with his mainstream/commercial popularity lasting approximately between the mid-1980s until the late-1990s) and his "rags-to-riches-to-rags-and-back saga", Burrell formed the Christian rap music group Holy Ghost Boys. Some songs produced were called "Word" and "B-Boy Chill". "The Wall", featuring Burrell (it was originally within the lyrics of this song he first identified himself as "K.B." and then eventually M.C. Hammer once it was produced), was later released by Jon Gibson (aka "J.G."). This was Contemporary Christian music's first rap hit ever (by anyone), in particular by a Caucasian (Gibson) and/or from a duo. The track appeared on Gibson's album Change of Heart (1988), and "Son of the King" showed up on Hammer's debut album Feel My Power (1987) as well as the re-released version Let's Get It Started (1988). Burrell, along with Tramaine Hawkins, performed with Gibson's band doing several concerts in various venues such as the Beverly Theatre in Beverly Hills.

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.
