...put yourself in Ed's shoes. He gets to play music he loves with his son and his brother! Michael is a fantastic harmonizing singer, an extremely average bassist, and apparently a true team player. Wolfgang is an outstanding bassist and from what I've seen, a pretty decent singer as well. There are three Van Halens in the band now, and that's probably a pretty big reason they're doing this at all. Wouldn't you do the same thing as well?
