Current issue of MOJO music magazine has a free CD with his version in the cover story on the Byrds.

I am a major Byrds fan always and from back the day
Oh yes. Ecclesiastics.
I was 7 or 8 years old when I first heard it. It almost sounded like something my Catholic church would be singing on Folk Music Night. Can be performed electric or fully acoustic.
