This to me is the definitive recording of the song 'All of Me'. Forget Frank Sinatra, JOE WILLIAMS did the best version.

Unfortunately this particular version was recorded specifically for the movie in 1984 and has as far as I know, never been released:

I think he recorded it once before decades earlier, but still nothing comes close to this. I have searched and searched. It's not even listed on the site of the music publishers under all the artists to which they own the rights. I'm at a complete loss.

Even worse, being one of my favourite comedy films I hear that a remake is in the works with Queen Latifah

is that the same song?

No, that's the version he did a lot earlier. Thanks for trying though.
