Ethan Hawke, Jimmy Fallon Play Bob Dylan Lullabies With Guitar: Watch

Ethan Hawke let Jimmy Fallon into his secret to getting his children to sleep at night — he sings them lullabies in the style of Bob Dylan!

The “Boyhood” star, who who is dad to daughters Clementine, 6, and Indiana, 3 (and also has two older kids, Maya, 16, and Levon, 12, with ex-wife Uma Thurman), explained to Fallon that singing lullabies unaccompanied wouldn't cut it. He had to do it while strumming guitar, and while singing in a Dylan voice.

Hawke, 44, then went on to show the host what he meant — starting with a fantastic rendition of "Rock-a-Bye Baby" complete with perfect Dylan-esque snarl.

Next, Fallon pulled out the guitar he just "happened to have" and proceeded to sing his daughter, Winnie, 20 months, a "Twinkle Twinkle" tune, just in case she was watching and struggling to drop off to sleep.
