I've still got that album -- for what it's worth. I've been singing it since I first bought the album. It's identical to the version Andrew Sullivan posts. I've never used the title "False Knight Upon the Road" which, as it's been pointed out is incorrect.
A little speculation regarding this ballad as Pete sang it. I've always wondered if the first verse is a corruption of the introductory verse of "The Fair Flower of Northumberland". North Cumberland -- from Northumberland. The story is very similar to the half-way point too. Hmmmm. Oh! Malcolm how I miss you! Cheers, Joy
