Thriller Live is a two-and-a-half-hour concert revue celebrating the music of The Jackson 5 and the solo work and life of Michael Jackson. It had already been performed in the United Kingdom, Germany, the Netherlands and Scandinavia before opening at the Lyric Theatre, London, on 21 January 2009. The show was conceived by Jackson family friend and author Adrian Grant.

"Speechless" is a song by the American recording artist Michael Jackson, included on his tenth studio album, Invincible (2001). It was only released as a promotional single in South Korea. The singer was inspired to write the ballad after a water balloon fight with children in Germany. Jackson collaborated on the production with musicians such as Jeremy Lubbock, Brad Buxer, Novi Novoq, Stuart Bradley and Bruce Swedien. Andraé Crouch and his gospel choir provided backing vocals.
