Denzel and Billy do boffo at the B.O.
Broadway’s auds went ga-ga over the marquees advertising Billy Crystal and Denzel Washington. Their respective shows, “700 Sundays” and “Julius Caesar,” grossed like big musicals, and set house records at the Broadhurst and Belasco. Thanks to premium tix, Crystal’s autobiographical one-person show was easily the season’s champ when it came to average price ticket. His usually went for at least $105; next in line, “Wicked” conjured up about $83.
