"In 1968, Jagger was reportedly inspired by John Lennon to write a working-class anthem. Featuring a cracked, soulful vocal from Richards during the intro, \"Salt of the Earth\" ascends to gospel reverie. Jagger's tributes to the common foot soldier and lowly of birth are tinged with harsh irony (\"They don't look real to me\"). But he was passionately sincere when the Stones played a transcendent version of the song (with tweaked lyrics) at the Concert for New York City a month after 9/11. \"I've got a feeling this town's gonna make it,\" Richards said with a massive grin."^^<http://www.w3.org/2001/XMLSchema#string>
