There are even three CD issues. The original Japanese pressed digipak and then after that the US pressed Myrrh Records jewel case release. And a couple of years ago Greg produced a reissue himself on Match Made In Heaven Music. Don't have that one, but I saw it for sale once. And I believe that if you order the CD directly from gregxvolz.com you will get this version.
I always assumed that they omitted the song from the vinyl release to promote the CD. It was included on the cassette release, so I'm not sure if that supports my theory or not.
I have two vinyl issues of The River Is Rising. One is the UK Myrrh Records pressing, which omits the song, the other is the US Myrrh Records pressing, which as far as I know also omits the song. And then there is a third vinyl release on A&M Records which I don't have, but which might have this song. Are you 100% sure, Brent?

I guess they left off Gethsemane because it was too long for the UK vinyl release. This hasn't been released on vinyl in the US. All the other formats (cassette, CD - US & UK) have the song.
