Ranger's Command MIDI is in the DT ("click to play" link). I kept playing it and then Prospect (from the online Southern Harmony) and then the RealAudio Seamen's Hymn link above, and I swear the first two are both very similar to the latter, but none of the three is the same as any of the three. Not perfectly the same, but maybe close enough to be arrangements of a single melody. Did Lloyd produce sheet music?
