I first heard Utah about 25 years ago at the Owen Sound Folk Festival. He appeared there a few years in a row. He and Gamble Rogers put on the best story telling workshop I'll ever see.
There are two tunes that stick in my head. I can't remember the titles, but they start out:
I was there when they opened the boxcar,
And found him stone dead on the floor...
and:
Is that the moon I see over there in the west,
Or just a headlight's glow, C&O Express?

He also did a bunch of trad songs like Cannonball Rag, Big rock Candy Mountain, Hallelujeah I'm a Bum...
A great performer. He was playing a big blonde Guild at the time.
