Bob LuPone, who as an actor earned a Tony Award nomination in the original run of “A Chorus Line” and played Tony Soprano’s family physician, and also helped found and lead the influential off-Broadway theater company MCC Theater for almost 40 years, has died. He was 76. LuPone, brother of Broadway icon Patti LuPone, died Saturday following a three-year battle with pancreatic cancer, according to Matt Ross Public Relations.
