Pioneering Parodist Allan Sherman; Tegan And Sara On 'Missed It Then, Love It Now'; Anna von Hausswolff

Summary: In this episode: Songwriter Allan Sherman rocketed to fame in 1963 with his unlikely hit “Hello Muddah, Hello Fadduh” — and then just as suddenly, he disappeared. We discuss the pioneering parodist with Mark Cohen, the author of Overweight Sensation: The Life and Comedy of Allan Sherman. Plus: All this week, we're asking for your “Missed It Then, Love It Now” picks. Tell us about the music you didn’t hear when it first came out, but now really love—and why. Pop duo and identical twin sisters Tegan and Sara give us their picks. And: Swedish singer and organist Anna von Hausswolff brings her band to the studio to play a haunting, moody set.
