You need to buy "The Mountain" CD that Earle and the McCourys did. I don't think there are any other recordings of it.If you want to hear Steve Earle, you should get Train A'Comin'. Then listen to "Tom Ames' Prayer." Before the last two verses, Norman Blake takes a guitar break. On cross-examination, Norman has stated that he didn't think up the break beforehand, he just "got the nod" and played what came out.
This may have been the greatest spontaneous flatpick guitar solo ever captured on a recording.
Or I may be indulging in hyperbole because I have a cold and my head is foggy.
You decide.
