Of course, a bifocal definition of art is that a) It's remembered after it's gone; b) It hasn't been dumped in the landfill, regardless of price at time of purchase.

A friend of mine is an artist who makes his living as an impressionist--Willard Bond. When I called him up a few minutes ago to comment that there was a song about him, he started singing "Willow, Weep for Me" before I could finish the line. [Willow is also his nickname.] You might have some luck tying nicknames to songs if you cannot find them under the original names.
