New Orleans-based, Swedish-born chanteuse Theresa Andersson will perform on this evening’s Late Night with Conan O’Brien. Last fall, Basin Street Records released her latest studio recording Hummingbird, Go! and she likely will perform one of its songs on the show. Andersson will remain in New York for a gig at Joe’s Pub on Friday night, with no other February dates in the offing. Conan’s other guests this evening will be Jon Hamm (_Mad Men_) and Ginnifer Goodwin (_Big Love_, He’s Just Not That Into You).
