This is the last known footage of Joan Crawford filmed at The Rainbow Room in New York City on September 23, 1974. Three years later Joan Crawford died of a heart attack at the age of 72.

The film is very grainy and its amazing that it ever got transferred to video and then uploaded at all.

Mid-way the audio kicks out for a minute but keep watching.  It all has a very disturbing sort of Sunset Blvd. type of vibe.
