The Jonas Brothers were an American rock and pop rock band.  Formed in 2005, they gained popularity from their appearances on the Disney Channel television network.  They consist of three brothers: Paul Kevin Jonas II, Joseph Adam Jonas, and Nicholas Jerry Jonas.  Raised in Wyckoff, New Jersey, the Jonas Brothers moved to Little Falls, New Jersey in 2005, where they wrote their first record that made its Hollywood release.  In the summer of 2008, they starred in the Disney Channel Original Movie "Camp Rock" and its sequel, "".  They also starred as Kevin, Joe, and Nick Lucas, the band JONAS, in their own Disney Channel series "JONAS", which was later re-branded for its second season as "Jonas L.A."

"Get Back" is a song performed by American singer Demi Lovato.  It was written by Lovato, Joe Jonas, Nick Jonas and Kevin Jonas and produced by the Jonas Brothers alongside John Fields, for Lovato's debut studio album, "Don't Forget".  The song features Jack Lawless on drums and John Taylor and the Jonas Brothers on guitars.  The initial writing of the song took place when Lovato wanted to write a song about getting back together with an old boyfriend, as opposed to writing mean or heartbroken songs.  "Get Back" was released as the album's lead single on August 12, 2008, by Hollywood Records.  Musically, the song is an upbeat rock song with a guitar-driven sound. Paul Kevin Jonas II (born November 5, 1987) is an American musician and actor.  He is the oldest member of the Jonas Brothers, a pop rock band created by the youngest brother Nick (although Kevin is often credited with creating the band).  In 2008, he appeared on "People" magazine's list of the Sexiest Men Alive by being a member of the 21 club.  On December 19, 2009, he married Danielle Deleasa, whom he met in the Bahamas during the summer of 2007.  Jonas and his wife later starred in their own E! reality series, "Married to Jonas," in 2012.  In early May 2014, he announced a small 5-month tour around the United States with younger brother Joe. "La La Land" is a song recorded by American singer Demi Lovato.  It was written by Lovato, Joe Jonas, Nick Jonas and Kevin Jonas and produced by the Jonas Brothers alongside John Fields, for Lovato's debut studio album, "Don't Forget" (2008).  It was released as the album's second single on April 10, 2009, through Hollywood Records.  "La La Land" is one of six songs on the album co-written by the Jonas Brothers, who also contributed backing vocals and guitars to the track.  Lovato said that she wrote the song about being yourself in Hollywood and not letting other people change who you are.  Musically, the song is a guitar-driven pop rock song and the lyrics speak of Lovato feeling "out of place" in Hollywood.
