Watch the CBS News Interview (the whole clip is great, but he starts talking about choral singing around 5:10)

The research on the benefits of singing in groups is stunning. Choral singing calms hearts rates and boosts endorphin levels. It improves lung function.
It increases pain thresholds and reduces the need for pain medication. It even alleviates symptoms of irritable bowel syndrome. Group singing—not just performances but also practices—increases the production of immunoglobulin, making it easier to fight infections. In fact, cancer patients who sing in choir show an improved immune response after just one rehearsal ...
Several studies demonstrate that choral singing delivers a significant boost to positive mood. It also lifts self-esteem while reducing feelings of stress and symptoms of depression. In enhances one’s sense of purpose and meaning and increases sensitivity toward others. And these effects come not from singing per se but from singing in a group.
