50-year high school reunion coming up

I graduated from high school fifty years ago this June. We’re having a reunion later in the year. I started to write our 50th reunion, but it isn’t, since we’ve only had a few reunions. So I’m calling it our 50-year reunion. I am a word fanatic, after all. Below is a photo of me along with several of my classmates. I’ll let you guess who is who.
