Not being a musician, I can't provide the chords.
But, the song can be heard on Al's CD 'Been on the Road so Long: the Alex Campbell Anthology' (2005), which a good sort of overview of his career (and a chance to hear the young Sandy Denny on backing vocals on one version of the title track!).
btw, just in case anyone is interested: Alex Campbell was born in 1931, not 1925. Alex's family knew this, obviously. His (ex)-wife believed that Al added 6 years to his age so that he could say that he had fought in WW2! I believe he had quite a sense of humour!
