I was watching a TV show this afternoon with James Taylor and the Dixie Chicks. One of the backup band was playing what was clearly an Overton whistle. Not sure of the key, looked too big to be a D, guessing A or Bb.
Do you rember what show and song it was?
Don’t recall the song. It was a CMT show called “Country Crossroads” and the point where I noticed it was the last song in the show, though it could have been in use earlier
