TimeOut NY does an annual list of each of the 10 hottest chorus guys and gals- and typically they're a diverse listing.
Though, in defense of this NYPost piece, it's really more about how these boys are developing a large fanbase despite being a (pretty) face in the crowd and not a principal role. Though in the case of Keenan-Bolger, he's been developing a social media presence for a while and hasn't really been a "chorus boy" in a while.
"...everyone finally shut up, and the audience could enjoy the beginning of the Anatevka Pogram in peace."
