I have no taping equipment. Don't even own a computer yet. It's always just me, my acoustic, my CD collection, and a CD player with a nice rewind to an exact spot capability. My version is based on Europe '72. If I tried to incorporate all the versions out there, I'd never get anything done.
Yes, have the C-D-E (in the middle of Jerry's second China Cat lead) but I've watched a U tube of China Cat (the one with the two dancing little girls at the start, great vid) and I've found that Jerry does the E jam at a position two frets below my position, which worries me, since it means my technique is different, and may wind up being an eventual stumbling block for me to really master his style. Jerry is based at the 7th fret and relying on a little pinky action whereas I am based at the 9th fret and everything works linearly across the fingerboard, and then I'll drop down the whole position to the 7th fret, just for a second before going back up to the 9th fret anchor again, just before the final move to the high E string where Jerry and I would once again be working it the same.
Now, remember, I am not playing with the flair that Jerry does, but I get close enough to pull it off with bravado. It sounds really good. When I pull it off after having warmed up on a few other songs, well, when I'm done with the whole thing, ending with Jerry's lingering note lick after Rider, I try not to touch any of the lower strings so that they ring as I lift the guitar away from me and rest it in a wing chair, still resonating.
I have incredible reverence for this song. I had known Weir's signature riff for over twenty years, but it wasn't until last summer, a year ago, that I set out on tackling Jerry's leads. Took me half the summer to work them in, and then a year to polish them up. Had to get a refret last winter trying to get a lot of Jerry's stuff down.
One tip: On Europe '72, calibrate your guitar tuner to 452 Hz = A 440 before tuning up. All of Europe '72 is 12 Hz higher than A = 440.
