Cast your fate to the Wind and Alma-Ville are still some favorites.
I also consider his arrangement of the peanuts music into a cohesive whole to be pretty masterful - its out of print now, but https://en.wikipedia.org/wiki/The_Charlie_Brown_Suite_%26_Ot...
So no idea what the song is about, unfortunately. I don't even know it has animation version.
(And I shouldn't have called it a song, as there are no words).
Linus and Lucy was recorded by the Vince Guaraldi Trio back in 1964.
They're all dead now, which is a shame.
But there's a brilliant modern recording, from 2016, that features the original drummer, Jerry Granelli: https://www.youtube.com/watch?v=OODA_K5hxyc
And it's definitely worth spending some time to give it a watch/listen. There's a lot more to that little tune than most people probably realize.
The genesis of Guaraldi's involvement was a 1963 documentary "A Boy Named Charlie Brown" which has nothing to do with the 1969 animated feature.
This was produced for TV but never aired, and recently surfaced on Youtube: https://youtu.be/UGAs5fZUvBM&t=425s
To complicate things further, Guaraldi released "Jazz Impressions of A Boy Named Charlie Brown" (once again, based on the 1963 documentary) but these recordings are not the same as the cues used in the documentary.
I can't get OTA and cut cable TV so I don't get a lot of things without effort that I don't generally go to.
(Sucks about the pbs part though, didn’t realize they’d stopped that.)
