Green Day frontman Billie Joe Armstrong is here with a cover of the self-isolation anthem “I Think We’re Alone Now”.

Armstrong joined Jimmy Fallon via video to perform his take on the 1960s song by Tommy James and the Shondells that became a huge hit in the 1980s when Tiffany covered it. Armstrong has been debuting covers every Monday online as part of a “No Fun Monday” series, previously performing “Manic Monday” with the Bangles’ Susanna Hoffs.
