My dad used to maintain one when I was but a mere pratt. The Treanon (sp?) Ballroom off 63rd in Chicago. Very kewl machine.

Since this particular console had three keyboards ("ranks"?), there was a Swell and a Great...and yes, there was a coupling stop labelled Swell to Great.

For 50 points and a chance at the Lightning Round...what color was the stop?
