“Weird Al” Yankovic Brings on the Alpocalypse

Al Yankovic talks about his career creating musical parodies, the release of his latest album, “Alpocalypse,” his first in five years, and his new children’s book When I Grow Up, about a boy who has many different ideas of what he wants to do when he grows up—from chef to snail trainer to gorilla masseuse. He’s also created an app based on the book.
