David Liebe Hart

Hart writes his own music, mostly about religion, aliens, women, trains, and his tragic love life. For six years he teamed up with his friend and fellow public-access television host Adam Papagan to create music together, with Hart writing lyrics and singing, and Papagan creating the music. They created four full albums and an EP. Since 2014, Hart has been collaborating and performing with producer/composer Jonah Mociun (AKA Th' Mole), developing a more electronic-oriented and carefully sculpted sound. With Mociun, Hart has released the mixtape Go Into The Light and the Teleportation Thru Space EP, with an official album, Astronaut, slated for release in January, 2015. Hart's songs from Tim and Eric are also featured on Awesome Record, Great Songs!.

He is vocal about his abstinence from smoking, alcohol, drugs and his dislike of rap music—but other parts of his life, especially since his arrival in Hollywood in 1976, are less clear. In interviews he revealed that he served as a cook in the U.S. Navy at one point in his life. Hart divorced his wife, Brigitte Unger, in 1993.

David Hart has been known to sell an album titled Christian Hymns And Songs Of Praise at shows during the Tim and Eric Awesome Tour 2008, as well as the 2009 tour. In Spring 2011, Hart and Papagan toured the East and West Coast with a newly formed band that played punk music exclusively, including new interpretations of their older material. The Best of David and Adam, a compilation cassette tape/download featuring music from David and Adam's five albums, was released by Cellar Hits in 2011.

Hart has frequently appeared on television shows The Del Talk Show, Tim and Eric Awesome Show, Great Job! as well as various other Abso Lutely productions and independent films.

He claims to have gotten his start in Hollywood performing with comedian Robin Williams and from making an appearance on The Gong Show in 1977.
