A poignant epistle to Nick Drake, the delicate folk jazz title track on Martyn's third solo LP emerged from a session "almost like a big jam"

Hard drinker with a soft heart who outshone many of his musical peers

Soulmates don't always feel the need to tell each other their feelings. It would take the singer-songwriter John Martyn the best part of four decades to let Danny Thompson know, "You're my best friend."

For decades he made some of the most beautiful music Scotland has ever produced, yet his life was haunted by demons which tore apart his marriage and drove him to drink. Now the album which documented his divorce in heartbreaking detail is to be celebrated at Celtic Connections. Jonny Jobson reflects on the grace and danger of a true genius.
