"He Came from the Mountains" is a Trailer album and as such of course not available on CD. Its first track is Rise Up Jock which was included in 1975 on the Electric Muse anthology; that's why I already knew it in my student days even if I got the HCftM album only a year ago.

I don't have (and didn't know of) "And Now It Is So Early", but I do have "Lovely in the Dances: Songs of Sydney Carter" (Plant Life, 1981)
as part of my Steeleye Span and John Kirkpatrick collection. It's a fine album.

MusicStack currently offers HCftM for £48.60. That might be a bit steep.
