Just some off the top of my head:
Underway (full version from "The vaudeville years")
October jam 1 (love the "news bulletin" riff)
Before the beginning (from "...Vaudelville..." AKA "Blues in B flat minor" on TVY)
Coming your way (from "Live in Boston - Remastered Vol. 3")
Book of miracles (the BN (& other "newer"...) lineup(s) should do more instrumentals but probably never will)
There aren't many of their instrumentals I DON'T like, I love all the ones you guys mentined too.
