Oh lord, that photo is a classic! Nothing like late 70s meets early puberty :D
I love the handsome-dudes in the back row, nr. 4 from left and farthest right. And the shell-shocked one farthest left in the next row :D I'm guessing he was friends with the Bill Gates lookalike 2nd from left in the front row. And look at the rebel in the denim jacket standing next to you! And those strappy sandals on the girl in the red dress in the front row... ooooh. Just beautiful.
