Green Day's Billie Joe Armstrong has been doing a quarantine cover series on YouTube for the past few weeks. He started it with his “I Think We’re Alone Now” cover two weeks ago, and he turned it into a weekly series with his cover of Johnny Thunders’ “You Can’t Put Your Arms Around A Memory” last week. “Welcome to No Fun Mondays. Going to release a cover song every week until we’re let back out into the world,” he wrote. Today’s cover is the Prince-written Bangles hit "Manic Monday" and the bands' Susanna Hoffs joins him on the video via split screen from her own home. Watch that, and the other two covers, below.
