You're very welcome Terri.
You mention the Potter recording about the bears, sorry for not being uptodate with this thread but you've lost me a little (easily done I'm afraid!). I presume you're referring to his BBC tv play "Beast with two backs" ?

I've not seen this film but thanks to you it's now on my Christmas List !. I don't know if it's ever been officially released on video. Searching the net I cannot yet find it on any freeview sites such as Youtube, there are many Potters already there and new films are always being uploaded so keep an eye out. A wellknown online auction site showed a Florida seller listing but not selling a VHS version only a few weeks ago, and it's available in the UK on dvd altho probably not HD quality of course. Some screen shots here.

Hope this helps, Jeff.

Please be assured I post these links only to try and assist fellow Foresters to access these important FoD archives, I'm not in any way connected with the various sellers.
