Oscars audience sings "Happy Birthday" to James Martin, actor with Down syndrome, as he accepts award

Irish actor James Martin attended the Oscars on Sunday and not only accepted an award, but celebrated his birthday with an audience full of stars. Martin, who has Down syndrome, starred in the best live action short winner "An Irish Goodbye," a film about two brothers who come together after their mother's death.

Martin took the stage with the film's directors, Ross White and Tom Berkeley, and his co-star Seamus O'Hara, to accept the award.

"This award is actually the second most important thing about today, because it's this man's birthday," Berkeley said, beckoning Martin up to the microphone. "He's out here in Hollywood, wearing a leopard print suit jacket, we'd love to use the rest of our time up here to sing for James."
