High on a Mountain is NOT an original... It was written by a friend of mine, Olabelle Reed. Furthur has tweeked the lyrics, but so has everyone else that has covered it. Marty Stewart won Ms Reed a Grammy in the 70s for his recording of it.
that being said, my vote goes to Big Bad Blues! =)
Just checked out her version of the song. Sounds great love how Furthur arranged it too!
