Sounded really familiar but I couldn’t quite place it. Thought it was from a harp album that I acquired years ago, but the performer (who was kind enough to write back) said "nay". Couldn’t find it on the web by this name, either.

Was hoping someone out there might be able to stir the cobwebs just enough to place where I might have heard this beautiful melody from?

Thanks.
