It's the latest edition of "No Fun Mondays"
from Stereogum
For today’s edition, he recruited a special guest in the form of the Bangles co-leader Susanna Hoffs to perform along with him (from their own separate houses) to her own hit song “Manic Monday.” Armstrong puts in a bit more production effort into these than your typical livestream — what else does he have to do, I guess — so it comes with a split-screen video featuring the two of them and some beefed-up playing.
