Prince has sadly left us, but his music remains. Since his passing more and more of once held back material (for fear of a lawsuit) is emerging online.
Here are two amazing clips from 1990 when Prince toured Japan. The first features a quick behind the scenes shot of Prince tactfully ditching the cameraman followed by an extended version of The Question of U/Electric Man with a Venus De Milo/Under The Cherry Moon piano intro.
