I was just praising Andy Irvine on another thread and then looked at this one. I'm still marvelling at how he flew from Japan to Dublin, was plonked in front of a camera in a pub and did an absolutely storming version of "Tom Joad" - quite a long song. I suppose in his case it was repetition AND past obsession with Woody.

As to verse order, I remember Simon Nicol regularly cocking up the verses of "John Barleycorn", to the point where he was applauded by the cognoscenti.
