Dirk Nowitzki singing

I heard a report about Dirk Nowitzki singing at the parade celebrating the Mavericks win for the NBA title. In fact, I heard him sing this morning! He should stick with basketball. He has a great voice. Unfortunately, it's in somebody else's throat. At one point Dirk hit a high C. But how often do you back into a spear? I'm still trying to decide if I'm glad Dallas won or Miami lost.
