Bumping to postulate that the two harp tracks in here likely are from an Emil Ascher-distributed library, as both were used in the Mercury Records Storyteller LP of Jack and the Beanstalk, and Mercury's Storyteller records are loaded with cues from libraries that Emil Ascher distributed (Video Moods, Conroy, Impress, etc.).
My theory is that they may have come from Conroy BM 275, as anecdotal evidence shows there's a suite called "Harp Music" by Bruce Campbell on that album (not to mention the aforementioned Jack and the Beanstalk record used one of Robert Sharples' Comedy Bridges from the very next album, BM 276).
Unfortunately, a vinyl rip of the album doesn't seem to have appeared online yet, and although it is catalogued on KPM's website, only one entry from Harp Music is available on it (as per usual, given the KPM website's sloppy handling of theme suites on the BM series), so the other parts of the suite are a complete mystery.
