a couple of fillers that have me clue less

[Roger McHenry]

This is not a tape/CD request, because I know to use the Resources for Traders site for that.     Hello. I recently purchased some tapes from a Flea Market and there is a filler on the 3rd tape that is "Run For The Roses" . It is only Jerry and I think a bass player and all it says is  "recorded at prison" and it seems that the next song would be "Ripple" by the way Jerry is tuning but it cuts off. The other filler is a Brent solo "Devil With A Blue Dress On"  Did he do this with the Dead?   Any information about these performances would be greatly appreciated [EMAIL PROTECTED]     THANKS ALOT
