Yes, I'd say Moz is an alpha male in that he's very much the leader of and provider for his charges -- employees mostly, but I believe he also takes care of his family financially.
And if you recall that article by the dude who worked as a roadie for Morrissey for about a day, then was fired (ostensibly for being/looking too old), it paints a picture of a whole group of people who follow Morrissey's rules about what they can eat, what they can say & do, how they should look (i.e. preferably like him). Moz is an alpha male not through violence but through his money and power of influence/fame.
This is not a criticism BTW, just an observation.
P.S. I thought many of the posts on the Russell Brand web site were very interesting, esp. that one who points out that Russell gets people's empathy through stereotypically female behaviour: flirting, being deferential, etc.
