Okiedokie, folkies....I'm gonna set the record straight for y'all. First of all, I love this tune. Second, I saw it at probably 10 of my 33 GD shows (I know that's a pretty small number in comparison to a bunch of you guys on this site, but it's a high percentage!!!). BUT, I did see it up close & personal about 8 of those 10 performances. I'm a Bob Weir-a-holic, when it comes to chords. Let's assume that we're talking about how BOBBY plays this tune, rather than how Jerry played it - especially since Garcia picked over the whole tune, for the most part!
Here's how it went from 1987 - 1995. Can't tell you EXACTLY how it was played before then, as my first show was in 87, but I'm pretty sure he hasn't changed too much, other than the intro, since they started playing it way back when.
The Asus4 you guys are talking about is incorrect. It's a bop back between A - G - A. I picked this up the first time I saw Bobby do it. When he DIDN'T go back to the G, he simply held the A...but mostly went back to the G....SO....
Me & my uncle went ridin' down
South Colorado - West Texas bound
We stopped over in Santa Fe
That bein' the point - just about halfway
Hey and you know it was the hottest part of the day
Finally, the last chord of the song is an Em9, but you play the F# note in the middle, rather than on top. So, I guess you could call it an Em/F#. It's played like this:
1 - o
2 - o
3 - o
4 - 4
5 - 2
6 - o
That funky sounding note (very prominent especially when they would transition to another 'cowboy' tune) is an F# played on the D string, if you're playing an open Em.
That's my $0.02
