"It's incredible that you can mix groups of people from all different years that knew the same music and sing," she said. "It's really inspiring."

According to Riegel, the Krokodiloes, Harvard's oldest a cappella group, helped publicize and form the Pitches.

Callbacks Win Quarterfinals

At the same time that the Pitches were celebrating their past, the Harvard-Radcliffe Callbacks were preparing for a competition.

Yesterday, the Callbacks placed first at the National Championship of College A Cappella at the University of New Hampshire at Durham.

"Everyone worked together and finally after all that hard work we just managed to channel and use that energy to show everyone what we can do," said Megan L. Gaffney '02, the business manager for the Callbacks.

After winning the quarterfinals against New England schools, the Callbacks will compete in the regional competition this Friday. The winning group will then proceed to the national championship in New York.

This is the first time the Callbacks have placed first in the New England competition, and the group has high hopes for the upcoming championships, Gaffney said.
