Three Hills' Prairie Bible Institute has released a pile of recordings associated with their campus over the years; this one was also released in a double-vinyl gatefold edition - we're counting ourselves lucky to have found it on cassette (even more so to have found both cassettes!). We don't think this is a staging of the Ralph Vaughn Williams musical version... or is it? We're not up on these things, as the only Sunday Skool we attended was at the Hi Fi.
