Alicia Keys and Broadway star Audra Macdonald have signed up to lead a tribute to late actress and civil rights activist Ruby Dee.

A memorial for the star will be held at the Riverside Church in New York on 20 September (14), and Keys and MACDonald will be among the famous faces saluting the movie and theatre great, who died in June (14), aged 91.

Dee's poetry and prose will be read by Angela Bassett, Tyne Daly, Phylicia Rashad, Pauletta Washington and Lynn Whitfield, among others, while Harry Belafonte will deliver a eulogy.
