You can’t beat a double dose of Jeff Tweedy to start the day — especially when it includes a brand-new Wilco song. That would be the yearning folk-rock slow-burner Tell Your Friends, which the singer-songwriter and his Chicago bandmates (plus assorted family members) performed from isolation on The Late Show With Stephen Colbert. Even better: It’s a fundraising track that you can score for $1 right now on Bandcamp via the link at the bottom of this page. Tell your friends, indeed — but don’t forget to enjoy the other half of today’s Tweedy two-fer: His solo rendition of Jesus, Etc., also from The Late Show. And speaking of etc.: Your other late-night TV musical offerings were the unstoppable Gary Clark Jr., working the acoustic guitar for a home-studio solo take on Low Down Rolling Stone, and Ben Platt crooning So Will I with a keyboard assist from Billie Eilish’s brother Finneas on The Late Late Show With James Corden. Now go spend a buck for a good cause.
