When I was a child my father would usually play the piano every Sunday afternoon. We, my brothers and sisters, loved it when he did. We would either sing, if we knew the words, or dance around like we knew how. lol
One of my Dad's favourite songs was, and still is, It's A Sin To Tell A Lie.
The clip above has a much faster tempo. But it is a great version I found on You Tube. His version was more like this one....a little slower paced. Listen to it here. Both are great. Hope you enjoy them.
