I'm curious to see if any of your grandparents went to old Milton Union from 1958 thru 1962, which is when I was there. I know a lot of them still live in Milton, now. I would think that they would remember me. If you google Arcadia High School Chanteurs, 2010, or earlier, you, or they, can see what I did for 37 years. Just curious, since I haven't been to a reunion for ten years.
I graduated from Milton Union in 1962 - way before show choirs! From what I've seen of your groups, they are quite good. There were about 82 in my graduating class - Milton is a lot different now, as is the choral program.
