Wayyyyy too many to name. It also depends on what kind of mood I'm in and if I want to hear an early pre-hiatus version or an extremely raunchy and crunchy later version.
I also agree with you stagger, the intensity of the jam says it all. Sometimes it's like a rocket that never quite takes off, other times it's like the rocket is flat out unstoppable.
Has anyone else noticed that alot of non-deadheads really like Jack Straw or is that just me?
EDIT: here's a link to an extremely nice JS jam that caspersvapors posted in another thread http://www.youtube.com/watch?v=pBjVZJfP ... ed&search=
