"Linus and Lucy" is a popular instrumental jazz standard written by American jazz pianist Vince Guaraldi. It serves as the main theme tune for the many Peanuts animated specials and is named for the two fictional siblings, Linus and Lucy Van Pelt.
The jazz standard was originally released on Guaraldi's album Jazz Impressions of A Boy Named Charlie Brown in 1964, but it gained its greatest exposure as part of A Charlie Brown Christmas soundtrack the following year.
It is one of the most recognizable pieces by Guaraldi and has gained status as the signature melody of the Peanuts franchise.
