It happened on a Copenhagen street in July of 1988. JoJo was playing his regular routine with his friends when Bruce walked by. JoJo called out to him, suggesting that he play a song with him. It ended up being three songs. The event was captured on video by two Danish guys, Michael Andersen and Thomas Frederiksen, who had just bought a video camera. This event is now a part of the documentary SPRINGSTEEN & I.
