Its Angus Young's Birthday (not THAT Angus Young).

And actually, the OTHER Angus Young we're talking about here isn't even around anymore! He was known as "Alan" Young (Angus was his British birth name which he changed), and he was the co-star of "Mr. Ed," the TV show from the '60's in black and white that featured a talking horse! Alan Young's character's name was "Wilbur." Angus "Alan" Young died just 2 years ago 2016, at 96, God Love him. "Hello, I'm Mr. Ed!"  (P.S. The voice of the talking horse "Mr. Ed", was that of Western actor Allan Lane, who unbelievably, was never credited on screen for being "Mr. Ed's" voice. Allan Lane died in 1973.)
