Soul, 50. Conscience, 100.

This week the Rolling Stones, the soul of rock 'n' roll, turned 50.

And Woody Guthrie, the conscience of rock 'n' roll, turned 100.

Gimme Shelter

Do Re Mi

Street Fighting Man

Vigilante Man

You Can't Always Get What You Want

Better World A' Comin'

Mannish Boy (with Muddy Waters)

Goin' Down The Road Feelin' Bad

Sympathy for the Devil

Because the Stones came up in the era of TV, there are plenty more videos of them. Here's one of two surviving film clips of Woody, playing the Ballad of John Henry's Hammer with Sonny Taylor and Brownie McGhee.

Swing on!
