Comment by Fokeman:
I think that these were Pegasus recordings which were recorded by Terry Brown.
See here... and were not necessarily Fontana recordings. Oh, I see what you mean. It says in the Notes "from the first two albums". I suppose the tracks were on the first two albums but these may have been separate recordings of the songs and tunes in their repertoire. What is also odd, is that the early records had no credits at all for who produced them, so in theory, this could have been the original recordings (which might have been...) produced by Terry Brown.
