Sadly, Sam Hinton died on Sept 10.

I agree absolutely about the missing note. "Paddifying" is a term which means altering the tuning of a harmonica in order to put that note back. It is generally done by tuning up the 3-blow reed by a whole tone.   The resulting tuning is called the Paddy Richter tuning, so-dubbed by Brendan Power, who is credited with having made the tuning popular.   We have been here before, you know.
