"I saw Marley a few months before he died in a concert at the Crystal Palace Bowl in South London. He was magisterial on that stage. His dreadlocks were shaken at the London Stock Exchange and at the Houses of Parliament. He stomped on the spot as if to put out the fire of despotism. He crooned some unforgettable lovers' lyrics as if to confirm that even the warrior has to love. His songs are anthems for me. They celebrate Africa, berate politicians, lament slavery, invigorate the spirit. Looking over the century as it closes, I see Marley up there with the best six popular songwriters - Gershwin, Bob Dylan, Michael Jackson, Billie Holiday, the Beatles... I know we all have our own lists."
