I found a song titled "Now I Am A Blind Fiddler And Far Away From Home" (words by C. H. Foss, music by A. Leopold Richard) copywritten in 1921 (source), but the song is definitely older than that; there was an (unfulfilled) request for the lyrics to the song "I am a Blind Fiddler and Far From My Home" dating to December 1912 (source).

I did find a reference to a song in June 1854 as follows (source):

"'It is here again!' uttered the patient suddenly, 'from ever so far off with some one else--I cannot recollect how long--many hundred years--he must have stolen from me--he was a lead-miner, I think in Sweden--no!--he went about everywhere, playing! It is I--I am a blind fiddler.' "

It's not clear if it's the same song requested here, but it certainly seems close.

Other than that, I only found references also citing the Sing Out issue from the source, or identical lyrics.
