"Jessica" is a rock instrumental written by Dickey Betts, guitarist and founding member of The Allman Brothers Band. Jessica was first released on the band's 1973 album Brothers and Sisters, and has subsequently been used in many different contexts. A January 2006 Wall Street Journal article referred to the piece as "a true national heirloom." It is widely known as the theme to the BBC Two motoring program Top Gear and its popular reformatted revival. The tune, along with "Ramblin' Man", is one of several tracks from the album which reflect a transition for the Allman Brothers foreshadowed by the stylistically similar Betts composition "Blue Sky" on the band's previous album, Eat a Peach, and accelerated with the deaths of band leader Duane Allman and bassist Berry Oakley. The song is named for Jessica Betts, the daughter of Dickey Betts and Sandy Bluesky.
