No not Harry Patch
The third of out three is the least well known by name, without even a Wikipedia page, but his music continues to endure long after his passing, and in terms of British popular culture his contribution was outstanding. His name was Harry Pitch.
In his obituary it stated “Harry was one of the handful of players who have turned harmonica playing into an art form. A player of enormous fluency and invention, his career has spanned six decades and innumerable gigs and sessions. He was one of Larry Adler´s favourite players.”
