Jason Mraz swept the winter chill off Saturday Night Live’s stage with his beach-ready love ditty “I’m Yours” this past weekend. Mraz fleshed out the arrangement with a horn section, and overcame minor troubles hitting the high notes on his chart-topping tune. He returned later with Colbie Caillat for a charming rendition of “Lucky,” the second single off last year’s We Sing. We Dance. We Steal Things.
