Mystery Symphony from the Mystery Guitar Man
A while ago, I watched a video in which the Mystery Guitar Man (MGM) asked his fans to send in videos of them playing various instruments. He asked that you play one note at a time, with a short break between notes. He said that he would create a video of a well known song, but MGM refused to let us know what song was in advance. Over 1,400 people responded, and MGM created this - the Mystery Symphony!!
