Awww,God Bless you Mr. Holdorf! I had Mr. Holdorf for Music Appreciation in 8th grade,in 1963,at Aptos. He was hilarious, sometimes unintentionally. His is the one teacher, out of all my school days, that I remember the most.Something always happened in that class! We had talent shows and I was just laughing my head off thinking of it. I think he sang off key too, or he played the piano off key, but he loved to play and sing. Great, great guy!
