Billie Joe Armstrong Covers a Song Every Week [VIDEO]

iHeartRadio Album Release Party With Green Day At The iHeartRadio Theater

When Billie Joe Armstrong covered Tommy James & The Shondells' "I Think I'm Alone Now" last week, we thought it was a one time thing. Thankfully, we were wrong. On Monday, the Green Day frontman not only shared another cover, but also announced he'd continue doing so every week in a series called "No Fun Mondays."
