Herbie Hancock; Astronaut Photos; Around the World with HONY

The Brian Lehrer Show is not live today, so we won't be taking any calls. As always, you can join the conversation online through our comments section (links below), on Facebook, or on Twitter through @BrianLehrer. We'll be back live on Monday, December 29th!

Legendary jazz musician (perhaps the greatest on Earth?) Herbie Hancock talks about his life and those who influenced him. Then, views of Earth from above by astronaut-musician-photographer Chris Hadfield. Plus: around the world with "Humans of New York" photographer Brandon Stanton; music inspired by and for protests; and New York City in 101 objects.
