I just found out and aquired a pilot of "Hazel" that has all the same cast except actor Edward Andrews plays Mr. B! It is the same script and is titled "Dorothy's Birthday" which was a season 1 episode. Harold looks much younger and it has a very cheap titled brief opening with the words Hazel three times in different fonts. I was very surprised in finding this because mainly I had no idea it even excisted, and of course thought Sony would have included it in the season one set...but of course why would they go the extra mile and be creative?

Where did you find it?

Never knew that existed!!!

Also, the current issue of Saturday Evening Post re-printed the very first Hazel cartoon! My first time ever seeing her in cartoon form.
