A Trip To Tin Pan Alley

The American Songbook – those classics from the first half of the 20th Century – has seen a resurgence in recent years. This hour, we’ll talk about why the music of Gershwin, Porter and other greats fell out of favor and how those tunes found a new audience with Ben Yagoda. He’s the author of “The B Side: The Death of Tin Pan Alley and the Rebirth of the Great American Song” (Riverhead Books), out tomorrow in paperback.
