To steer this a little off track...
Let's switch to Mitch Miller. Is there any Sing Along with Mitch TV Christmas special that ever aired. If so, any copies out there? The only thing I've come across is this http://www.amazon.com/Holiday-Sing-A...1835471&sr=1-2
!!! From the preview that plays on that page it looks as though someone just recorded a TV playing the VHS version.
UPDATE: Due to my concerns, I was able to get a discounted copy of the Mitch Miller Christmas show form the second link. It was well worth the money. Not the greates quality video, but audio is clear - Great.
I'm still waiting on the non-PAL copy of the Ray Conniff special from Belgium. I hope it gets here before Christmas!!
