Prince at Super Bowl XLI - All Along the Watchtower into Best of You into Purple Rain, with the rain pouring down hard!
Right before the start of the show, the producer/director, Don Mischer, called Prince on the phone from the production truck, "I want you to know it's raining!" Prince: "Yes, it's raining." Mischer: "And are you okay?" Prince: "Can you make it rain HARDER?!" Now turn it up LOUD and click on the headphones.
