Dicho, you had not earlier mentioned Cyberhymnal as your source.

The midi sounds like an arrangement of Edson's arrangement. I don't see anything to indicate it's directly from Bach's supposed orginal. Cyberhymnal does not cite sources & I have found it unreliable enough on hymns I do know that I'd want to be able to verify it's sources.

Is anyone who knows "How Tedious" actually familiar with this Bach Cantata that is supposed to be the original? How close are they, really. OTOH lots of "Bach" Chorales are actually arrangements of hymns with known composers so his Cantata could certainly be an arrangement of an existing tune.

My question is would a rural American composer like Edson really know Bach's music? Edson himself wrote 2 of the all time great fuging tunes: Lenox & Bridgewater.

Hmm, I think it's time to go solicit information from my hymn guru.

2. William Cowper & John Newton wrote the hymns in the Olney hymn book. While I don't remember which it was, the hymns by one were indicated while the rest were unmarked. Most were by Newton, but 68 were by Cowper, so I suspect it's the Cowper hymns that were marked.

The edition of Olney Hymns used by CCEL apparently added the attributions to every hymn. That's probably as close to clear information as to source as you're likely to get. The 68 by Cowper were also included in his Complete Poetical Works & can act as a cross check with the full text of Olney. "How tedious" is not there.
