In addition to the albums mentioned in the post, a couple of other of Archie's albums spring to mind.
One that should be easily obtainable is "The Man with a Rhyme" Folk-legacy FSS-61. (Sandy Paton is a familiar name around here)
Harder to find - Archie Fisher XTRA 1070 (this also got a Celtic Music release), and "The Fate o' Charlie" again with Barbara D. This was on Trailer LED 3002. As with all the Leader records Celtic Music is sitting on the tapes ( see Nic Jones threads for the whole story).
Other than these Archie's recording is limited to Topic's Fisher Family album and numerous compilations (all containing exclusive recordings of Archie or Ray&Archie) on Topic, Decca and Waverly.
Hope this helps
