If you have watched any of the
animated Peanuts shows and have heard the catchy
piano tune that goes especially well with
Snoopy running around and everybody in the gang pretty much having fun then you probably are hearing the Linus and Lucy song.
Originally done by the Vince Guaraldi Trio as a piano and percussions song, it was perfectly redone by George Winston as a solo piano piece in his Album Linus and Lucy the music of Vince Guaraldi.
This song by itself best describes the Peanuts animated shows. Along with Skating, The Charlie Brown All Stars, and Monterrey.
