The BBC is doing a special honouring Canada's Joni Mitchell on their Radio 4 network. And if you're a fan, the good news is that the BBC's radio properties are available online and are not geoblocked. The special airs on the singer's 80th birthday, November 4th, and will be on its website for at least six weeks shortly afterwards. 

"It will incorporate previously unheard interviews, studio out takes, rare demo recordings and archive dating back to Mitchell’s very first radio interview recorded in 1964, this programme is the story of Joni’s life and career – told in her own words."
