When you don't have your band members around - get your kids involved!
James Corden caught up with Billie Joe Armstrong safe from quarantine, and enquired after his Green Day bandmates, and the inspiration behind his "No Fun Mondays."
Then Billie Joe and his sons Jakob and Joey performed a really cool rendition of Tommy James and The Shondells I Think We're Alone Now.
His sons played the bass and drums, while Billie Joe crooned the tune and played lead guitar.
And we love it.
