"Linus and Lucy" is the iconic jazz piano theme composed by Vince Guaraldi (1928–1976) for the Peanuts animated television specials, first appearing in "A Charlie Brown Christmas" (1965). With its distinctive boogie-woogie bass line, bright piano melody, and swinging rhythm, it became one of the most recognizable pieces of American popular music and a beloved symbol of the Peanuts franchise.
