Everyone knows the "statue of a critic" quote, but here's a quote I encountered a while back by Sibelius that I thought was funny:

"It is difficult to keep company with artists. You have to choose businessmen if you want to converse, because artists only talk about money."
--Jean Sibelius as reported by Bengt von Trne

A hundred years later, this quote could be aptly adjusted to read:

"... orchestra players only talk about money."

That's a bit odd; I thought the businessman's business is money-making... but I suppose the artist is harder-put to get money. Interesting.
