The Kroks were founded in 1946, when four members of the
Hasty Pudding Club, popular for its drag musical theater productions, began singing popular hits of their time in four-part harmony. Since 1989 the group has appeared four times at
Carnegie Hall: debuting there to a sold-out audience in 1989 at a concert to benefit world hunger, in the spring of 1995 in an
American Red Cross benefit, in May 1998 in a concert for
Mothers Against Drunk Driving, and most recently at Zankel Hall in March 2008. In 1993, the Kroks performed as the
opening act at the New England Inaugural Ball celebrating the inauguration of US President
Bill Clinton. In 1997, the Kroks performed at the June 30
Hong Kong handover ceremonies commemorating the return of Hong Kong to China. ==Notable alumni==
