Philadelphia: Condoleezza Rice is no stranger to the whims of royalty. So when the Queen of Soul herself, Aretha Franklin, decided the two should get together to play a song or two for charity, it was decreed.
The former US secretary of state and Franklin took the stage at Philadelphia's Mann Music Center in a rare duet for Rice, the classically trained pianist, and Franklin.
Their aim was to raise money for urban children and awareness for music and the arts.
Their three-hour concert with the Philadelphia Orchestra overflowed with Franklin's catalog of hits and arias from the world of opera and classical music.
Rice, better known as a diplomat and national security adviser, accompanied Franklin singing her hit I Say A Little Prayer as well as My Country 'Tis of Thee.
