The 1909 Fenner book is available for free viewing and download at Google Books:

The Hymn Site offers some nice harmonized MIDIs; see this web page:
http://www.hymnsite.com/fws/hymn.cgi?2096

The Cyber Hymnal also has a nice harmonized MIDI and score (available in both PDF and NWC formats).

Below I've transcribed the (melody-only) score from Fenner into ABC; feed it to the folkinfo.org ABC Converter to generate a MIDI and PDF score. You'll probably want to transpose the output, since G-flat isn't the most instrument-friendly key.
