key levelling -- crown?

[Farrell]

How many times has the name Steinway been mentioned in this thread?
Marketing Department. Just do something a little different, even if for no
reason. Then people will need to say Steinway this, Steinway that, why does
Steinway do it that way, why don't others....... And there ya go to have the
others, and then you have Steinway. I guarantee you that back in 1878 there
were a bunch of three piece suits sitting around the big walnut table at
Steinway trying to figure out ways to put the name Steinway on eveyone's
lips.

Just my cynical take.
