One man deserves the blame

Pretty sure we've all heard Tom Lehrer's "Lobachevsky," right? A song about plagiarism where all the bits of melody are stolen from other songs.

I just learned that even the idea for the song was stolen! Danny Kaye used to do a routine about the Russian theatrical director Konstantin Stanislavsky, and it's the obvious basis for the Lehrer song. Lehrer credited Kaye in his intro to the song, which was left off the version on the album I listened to as a kid, but it's on Genius.com.
