More What's My Line?

Okay, let's head back to What's My Line? -- but not for a Mystery Guest.  No...for TWO Mystery Guests.  Actually, only one is official, but that's only semantics.  The first special guest is special enough to require that the panelists wear blindfolds, and that's because it's ​Walter Cronkite.  He comes at long at the 3:30 mark, if you want to jumpt to him.  As you'll seen, he's having a fun time here.  He only disguises his voice a very little, but still they don’t get it right off, even given how recognizable that voice is.  And then around the 15-minute mark, you can jump forward and catch the official Mystery Guest -- Art Carney.
