17. The Beatles: 'Revolution' – One of The Beatles' rockier numbers, the Lennon/McCartney penned track was inspired by the Parisian riots of May 1968 when students took to the streets and the largest ever economic strike in an industrialised country took place. Directly addressing and prompting the world's young revolutionaries, Lennon pertinently sings: “You say you want a revolution, Well, you know, We all want to change the world” and perhaps the most inspired lyrics: “But if you go carrying pictures of chairman Mao, You ain't going to make it with anyone anyhow.”
