Were can you download Rupert the bear and the frog song video for free?

The 2 major sources of free Rupert the Bear downloads are YouTube, where they come in three parts, and GUBA and its correlated site Flickpeek. There are many sources of the Frog Song by Paul McCartney, but I haven't found one that has both the beginning and the end. AOL.com seems to have most of the video and the best color. Lists of the 1970 Rupert episodes on Big Cartoon Data Base and TV.com, tho nobodies number sets quite match. NOW- can anybody help me find the MISSING episodes- Ginger;Uncle Grizzly, Ottoline, etc.?
