Zulu's 'Tip-Toe' Choir Competition

Every Saturday night in a gritty YMCA in the South African city of Durban, men put on finely-pressed suits, drink cheap beer and compete in an a cappella Zulu choir competition called isicathamiya. They're sometimes called the "tip-toe guys". Isicathamiya means "in a stalking mood" and it refers to the slow deliberate dance moves the men do in unison while harmonizing. NPR's Jason Beaubien reports.
