Billy Bragg, Joe Henry and Grace Petrie celebrate Woody Guthrie's Centenary

This year sees the 100th anniversary of Woody Guthrie's birth - one of the most influential figures in popular music. As part of a year of celebration, Billy Bragg curates and performs in four shows in England, Ireland, Scotland and Wales which focus entirely on the legacy of Woody Guthrie.

Bragg has invited singer-songwriter Joe Henry and rising indie-folk star Grace Petrie along to join him in the celebrations.

Guthrie inspired Bob Dylan and a generation of topical singer-songwriters in the
1960s, and even had an influence on punk with Joe Strummer modelling himself on Guthrie and asking friends to call him Woody as a teenager.
