From Puff Daddy (P. Diddy, Diddy) to Ol’ Dirty Bastard (Dirt McGirt, Big Baby Jesus, Lionel P. Fancypants), there is a long tradition of rappers changing their names for no particular reason.  But it was still a shock to learn earlier this week that Snoop Dogg had changed his name to “Snoop Lion” — especially since he did it at the urging of a Jamaican priest, and from now on will perform only reggae, not hip hop. The whole thing is so dramatic and bizarre that it’s worthy of its own Broadway musical! Seriously!
