The youngest is 84, the oldest 95, and none are ready to give up dancing yet. The Silver Belles are a group of classy, sassy hoofers who met in the 1930s as chorus dancers at the famed Apollo and Cotton Clubs. There, they learned their trade and performed with legendary bandleaders and performers including Cab Calloway, Duke Ellington and Ella Fitzgerald. They also formed lifelong friendships. When the dancers met up again in 1985, they discovered that they'd lost none of their moves — and their performances packed 'em in at concert halls in New York.
