Just to name a few I haven't seen yet:

Interstellar Overdrive - Pink Floyd
Flying - the Beatles (very groovy song, it always relaxes me)
Moby Dick - Led Zep

And also, a bunch of Greasy Knots jams that turned out pretty cool, like "Separation," "Bassline AB200," and one we did last night with me playing bass and Michael playing guitar which I like to call "F-f-f-funk."
