I was looking up this Si Kahn song because my wife has taken to singing it. To my delight, I was left in awe by BG banjo picker Jens Kruger's brilliant CH backup.
Another opinioned comment: Si Kahn's song writing is head and shoulders above nearly all the singer/songwriter stuff that came out of the FOLK revival. Same for the Kruger Brothers instrumental work. Had what you are listening to here been the standard for the FOLK revival, the FOLK revival would not have the irrelevant legacy that disparages it.
