My Dad was the one who taught me to sing.   On trips to Smith Mtn.. VA. he taught me tons of songs.  One he taught me was "Camptown Races" but as soon as I learned the words, I would only let him sing the "Doo Dahs".  That became our thing.  And every card and letter and even an engraved compact was signed "Doo Dah Daddy."  I will always be grateful for his gift to me.  It changed my life. I love you Doo Dah Daddy.
