Tune in to WNYC at 2pm this afternoon, when I debate Mark N. Grant, author of “The Rise and Fall of the Broadway Musical,” on “Soundcheck.” The topic: rock on the Great White Way. Does it belong there? Has it ruined the art of the musical? Is it going to save the art of the musical?

Host John Schaeffer has started the debate on his blog. “Not being much of a Broadway fan myself,” he writes, “I’m tempted to just assert that no kind of music goes well with Broadway.” Fighting words, John, fighting words!
