The dream would be if the Islamic Cat Stevens and the Jewish Bob Dylan were to do a world tour together, for the purpose of promoting peace between peoples. (And I can't think of any Christian artists of their caliber.)
In the article at the URL, I completely relate to Cat' s statement that the biggest problem that he had to deal with as a superstar pop/rock musician was his own ego. Though not a celebrity, at my age, I am acutely aware of the problems posed by my ego. And like him, I think I now have it more under control than not.
Cat also speaks of the burden of being a sex symbol. Now that's something I have not had to contend with!
