Hi Robyn!
Nothing gets lost on the web!
I just recorded my version of this song, hoping that I could still remember the melody from Val's performance 45 years ago! How's that for musical memory? :)
I'm still in contact with John and Susan Sutherland, who continue to be active on the NZ folk scene. I'm sure they'll know Phil Garland, and vice versa.
Alas, my old mate, Bruce King died a couple of years ago in Nelson. I learnt quite a few songs from Bruce in the mid sixties, when he lived in Christchurch.

Cheers, and regards from Germany!
Peter
