Nice to nail this one down.

I'd like to know more about Graeme Miles. Is he Australian?

From The Living Tradition:

"Another of Martyn's favourite songsmiths is Graeme Miles and he has recorded several, one such is 'Shepherd On The Fell'. "It's a really good song, one he wrote in the mid-60s, '65 I think, and, like Eric Bogle, he started off with some of the best ones, his first song was 'Sea Coal', written in 1949!" Martyn also recalls an early tribute to the magic of Graeme's writing skills... "

Cheerily,
Charley Noble
