Kevin was right: he _did_ write the book, and I sat next to him at the
sale.  What does it all mean, however?  Obviously, in my opinion, this:

Two keen buyers, with more money than information on what they're
trying to buy, met at the same sale, had a rush of blood to the head
and went all out to secure the item.   Hardly needs to be said, really.

Does it mean that Concert Roller Organs are worth thousands of dollars?
Yes, but only very occasionally.
