Here's a cute, quick (two-minute) rendition of the Michael Buble hit. Heartfelt lyrics recognize that despite living in crazy times, a special person in your life makes it worthwhile. No solo or vocal percussion required---this contemporary a cappella arrangement covers the tune with the choir and incorporates aspirated "chk's" as built-in rhythm. Additionally, "doom's" in the lowest voice part layout a supportive bass line, and a catchy "La la" refrain stays in the ear long after the final cutoff. Equally effective with large groups or small ensembles.
