This is a terrific song in all respects with one fatal flaw (if you happen to be a car guy)... the line "47 Ford flathead four". From 1932 until 1951 ALL domestic Ford cars and trucks had 8 cylinder engines. The only 4 cylinder engines were in UK Fords.
Great song...But to correct the previous comment. The 1932 thru 34 Ford model B had a flat head four. In 1941 thru 51 a flat head six was offered....But why get technical, just enjoy the tune.
