When teaching in China, we made friends with a couple from Minneapolis, and they told a story they swore blind was true.
They had a friend who was walking somewhere in the city one day during a downpour, and suddenly a limousine pulls up next to him. The window rolls down, and Prince's head pops out, and he offers the guy a lift. So he got into the limo, and Prince told the driver where to go, and he was sat in the back of this limo listening to an album of his own work (I don't think we got to the bottom of which album). Soon, they arrived at the guy's destination and he thanked Prince and went to open the door, at which point Prince shouted something along the lines of 'Stop! Listen to the end of the song!' So they both sat there listening to the end of this song in a kind of awkward silence
