Sincere Sugar

Happy birthday, Christine McGuire, oldest of the three McGuire Sisters. They were one of those pre-rock and roll girl groups that lasted into the rock era. In fact, they had a pretty smooth transition, covering the Moonglow's R&B hit "Sincerely," turning it into one of the biggest hits of the era:



A couple years later they had another #1, this time a little bouncier. (The tune seems to come partly from Chico Marx's theme "I'm Daffy Over You.")
