On Tuesday, Bob Dylan, Joan Baez, Smokey Robinson, John Mellencamp, the Blind Boys of Alabama, and others gathered at the White House for “In Performance at the White House: A Celebration of Music from the Civil Rights Movement.” And while Mr. Dylan and Ms. Baez didn’t actually reunite (ugh), both did perform; the former offered a rendition of “The Times They Are A-Changin’”, while the latter reportedly led a sing-a-long of “We Shall Overcome”. The whole thing will re-broadcast tonight on PBS at 8PM EST, but, for the sake of your sanity, let us offer an early preview (via TDS) of Dylan’s performance.
