Several clips are available on YouTube, including Shelly Burch's excellent "Bill".
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
-John Guare, Landscape of the Body
While I know it was Papermill, didn't it actualy air as part of the Live from Lincoln Center program--whose programming is still tied up in rights issues and usually is only available due to actor contracts, etc, to be shown twice by each PBS station (Light in the Piazza, NYCO's Night Music, Contact, South Pacific and a ton of other interesting stuff fall into this category too, hence no DVD).
A while back they released a press release for Live from... s anniversary (maybe three years back?) and said they WOULD manage to release some classics from the show finally on DVD, but I don't think anything has come of it yet.
While what I've seen won't eclipse my memories of the wonderful Hal Prince revival, it does look like one of the better recent Show Boats and I would love to be able to see it in full somehow, somewhere. I know at the time Papermill worked hard to try to create a more authentic, return to the original production type of Show Boat and I believed worked a lot with Kreuger and McGlinn (who wrote that great 70s Show Boat history, and both did the epic 3CD recording).
I love the clip of "Can't Help Lovin' That Man." It's such a wonderfully infectious number, and a key scene that shows the relationships between Julie/Magnolia and Joe/Queenie. I hated how that song was turned into a dirge for the '51 film version,, and how so many covers of the song after copied that style. Totally takes away the fun from the song.
