This 1973 song, first performed by Donny Hathaway, was originally written about his troubled life. The song evolved into a plea for human rights, fitting many occasions up until now.

Aretha Franklin sang “Some Day We’ll All be Free” at the Lincoln Memorial for a celebration of Bill Clinton’s inauguration. As a bonus Aretha followed that with her classic, “Respect,” the 1967 cover of Otis Redding’s song that she made one of the most famous appeals ever.

This continues a survey of songs of the Civil Rights era, leading up to the dedication of the Rev. Martin L. King Jr. memorial next Sunday. The memorial is now open to the public through Thursday but then closes in preparation for the dedication program.

Here’s Aretha.
