The bassline from Part I, the Vince Guaraldi Charlie Brown sounding bassline. I'm very unsure of what the time signature is, as there seems to be an extra half-beat every other measure (sometimes every third measure, sometimes not at all.) It's probably just in 4/4 with some cleverly placed accents and upbeats but I'm just not clear on it. I can play it though I think, and if my ear isn't lying to me it should be

A E F# E F# Ab (Ab)

With the second Ab only occuring when that extra half-beat appears. Any idea from the musician crowd? Phil, I'm looking at you...

Upon more listening, it turns out that what I wrote up there is not actually the bassline but some amalgam I created of the piano part and bassline that works as a bassline.

A E F# E F# Ab (Ab)
1 & 2 uh 3 & (uh)
