The singer told Radio.com that she's at her most creative in the wee hours of the night. Rarely does she write a song before 2 a.m. "At those hours I'm at my most relaxed," she explained. "Everyone else is asleep, you have nothing to worry about. I feel my mind is a lot freer."

While relaxing in the back seat of the car, she managed to make out her first U.K. single, "Heaven" � off her debut, Our Version Of Events � playing faintly on the radio.

Though she was riding by herself, she wasn't completely alone. She shared the momentous occasion with the cabbie, whom Sand� admitted had no idea who she was. To his defense, Sand� had not become the household name she is now. Either way, the moment became a memorable one.
