Just call them angels of the morning — and yes, I know they’re actually angels of the Late-Night TV Music world, but I’m writing this at 7 a.m., so work with me, will ya? After all, it’s not like I’ve got that much to work with. Thursday brought us just two sweet performances: Sasha Sloan offering her seductive Lies on The Tonight Show Starring Jimmy Fallon, and Alicia Keys wrapping up her week-long CBS parking-lot residency with Underdog on The Late Late Show With James Corden. Now slowly turn away from me. No need for the cheek-touching. That would just be creepy.
