The Forum "The River Is Wide" on Rev-Ola - big CD error?

I have this CD, which has (and lists) 19 tracks. The last three tracks are all listed as "alternate versions" of "The River Is Wide," and tracks 18 & 19 are just that. Track 17 is, however, an instrumental which bears no relation to "The River Is Wide." And sadly, there does not appear to be a missing version of "The River Is Wide" on there, so this situation is more than a simple error in listing the song order. Plus, as it's an instrumental, this mystery track is especially hard to identify. I've looked through discographies in hopes of identifying this track (hoping there'd be one odd track not listed on the CD) . . . but nothing. Can anyone help?
