Civil rights activist Medgar Evers was assassinated in Mississippi in June 1963. This summer will mark the 50th anniversary of his death, and Evers' wife, Myrlie Evers-Williams, joins AARP Radio host Mike Cuthbert to talk about the changes and racial progress that has happened in the half-century since.

Evers-Williams, an accomplished journalist, activist and former chairwoman of the NAACP, delivered the invocation at President Barack Obama's second inauguration. A woman of many accomplishments and talents, in December she played a classical piano concert at Carnegie Hall, fulfilling — at age 79 — a lifelong ambition.

"Dreams do come true," she says.
