CHARLESTON, W.Va. -- Mitchel Kawash says he owes his freshman roommate big-time.
"I was just walking past a sign about an a cappella group at school, and my roommate said, 'You sing, right? I've heard you in the shower,'" Kawash said, now a senior at Yale University.
That was the day that led the George Washington High School graduate to get involved in singing groups on campus and eventually become a member of the Yale Whiffenpoofs -- the nation's oldest a cappella group that travels the world performing.
"If you're into a cappella at all, you dream of becoming a Whiffenpoof," Kawash said. "I don't think I've ever been as nervous in my life as I was the day I tried out to be a Whiff."
Fourteen senior Yale men are annually chosen to be a part of the prestigious group, which was founded in 1909 and is one of the Ivy League school's most celebrated traditions.
The student singers take a year off from classes for strict rehearsals in preparation for a world tour.
This year, Kawash and his fellow Whiffs performed on all seven continents -- yes, Antarctica too -- and even stopped in his hometown to play at the Clay Center, in March.
