I also keep my twelve string tuned to standard D
I have a guitar that I do this with as well. Some great songs to play, that were originally played this way include:
Hey Hey My My
Rockin in the Free world -all Neil Young
The Joker - Steve Miller
Sunday Morning - Velvet Underground
And, of course, if you capo at the 2nd fret, you're back in standard E tuning.
See, I'm with you jimcck. Jerry MUST have used alternative tunings as he was such a guitaraholic. He played peddle steel, slide, banjo, etc. I'm just surprised there isn't much out there to back this up.
Oh, and I like open E better than D because it's easier to tune to and while it does create more stress on the neck, a well-made guitar can handle it.
