The band started as a solo project for Nick Jonas. At the age of 7, Nicholas began performing on Broadway. He has acted in several plays, including A Christmas Carol (in 2000 as Tiny Tim and as Scrooge at eight), Annie Get Your Gun (in 2001 as Little Jake), Beauty and the Beast (in 2002 as Chip), and Les Misérables (in 2003 as Gavroche). After Les Misérables closed, he performed in The Sound of Music (as Kurt) at the Paper Mill Playhouse. In 2002 while performing in Beauty and the Beast, Nick had written a song with his father called "Joy to the World (A Christmas Prayer)". With background vocals from the Beauty and the Beast cast, Nick performed the song on the 2002 annual Broadway "Equity Fights AIDS" album, Broadway's Greatest Gifts: Carols for a Cure, Vol. 4. In November 2003, INO Records received a demo copy of "Joy to the World (A Christmas Prayer)". The label released the song to Christian radio, where it quickly became popular on Record & Radio's Christian Adult Contemporary Chart. While Nick was working on his solo project, Joe followed in his footsteps to Broadway, appearing in Baz Lurhmann's production of La bohème. According to Nick, this was also the first year the brothers started writing songs together. The Jonas Brothers made their acting debut in season 2 of the popular Disney Channel Original Series, Hannah Montana, where they guest starred on the episode, "Me and Mr. Jonas and Mr. Jonas and Mr. Jonas". Soon after, they collaborated with Miley Cyrus again on her 3D Concert Film, Hannah Montana & Miley Cyrus: Best of Both Worlds Concert, which takes place during the tour for which they were Cyrus' opening act. While on the Look Me in the Eyes Tour, the Jonas Brothers filmed a Disney Channel reality short series entitled, Jonas Brothers: Living the Dream, that premiered on the Disney Channel on May 16, 2008. The show, which ran until September 5, 2008, documents their lives while on tour. It features clips of the band rehearsing, traveling, performing, studying, and their personal life with their family and friends. The Jonas Brothers also did a special, half-hour variety show on the Disney Channel special entitled, Studio DC: Almost Live, that features The Muppets and other Disney Channel stars.
