Laura - I have some good old photos from the Square, late 1950s to early 1960s including Eric Weissberg, Marshall Brickman, Roger Sprung, Bob Yellin, Paul Prestopino, Winnie Winston, Lionel Kilberg, Danny Z,Artie Rose,Tom Paley,Jules Hansen, my brother Willie, "The Professor" me,et al.   If you tell me how to e-mail them, I'd be happy to do so. If you want to e-mail me directly, go to

and click on "contact D,L & W" at the bottom of the page.

One of the best articles on the Square was written by Jay Feldman for Bluegrass Unlimited a while back, covering many of the above folk, plus the famous "riot". See http://www.jfeldman.com/square.pdf

There's also a documentary film on the Sunday riot.

More ideas if you contact me.
