On the Night of April 16, 1973 Chevrolet and ABC presented the world premiere of an hour from Paul McCartney that promised "Yesterday", "Michelle", "Long Tall Sally", and a medley of half a dozen Beatles songs.       As we soon come upon the forty-fifth anniversary of that airing, history has not lived up to that initial anticipation.     This week, the WTWF guys along with special guest Tom Hunyady (of the "2Legs" McCartney podcast) let the YouTube warm up and spend the hour commenting and providing facts, sarcasm, humor and select audio from the special (during those times the special held our interest, or we couldn't think of anything to say!)
