Buster Keaton Sings

This is a joy.  It's from a privately made tape at a party in 1962 where Buster Keaton was attending and ended up entertaining the guests.  This is just the first two minutes or so, and has the famous silent comedian singing the old song, "You Made Me Love You," with the crowd joining in, but you can hear his bass voice clearly in the lead.  But then, after going through it once, he then launches into a parody version, that uses high-tones fancy lyrics in place of the original.  And he occasionally sports a British accent for effect.

The whole recording runs much longer, with other little songs and stories.  You can find the whole thing here (it goes for 24 minutes) but this for me is one of the highlights.
