Iain McGeachy, alias John Martyn is from Dalintober fishing stock and if I remember correctly there is some background info on this in Angus Martin's book about Kilkerran Graveyard. Bob McGeachy in Carradale is his first cousin but he will have other relations in the area as well.
Back in the day, he used to come to Carradale for his holidays every year, sometimes with legendary double bassist Danny Thompson who featured on many of his classic albums and live shows. Strangely, they came on the service bus to go fishing, and one time famously, were getting a lift from Lochgilphead as some of the Crofters were up at a Dick Gaughan concert, so they ended up doing a floor-spot in Lochgilphead Folk Club. Apparently Dick was only too glad to lend JM his guitar and the Janny from the school was summoned to get a double bass for DT. When they were announced by the organiser, who still couldn't believe what was happening, Danny got up and said something like " The ******'s a way for a fish supper" and proceeded to terrorise the audience with a performance of the legendary Haitian War Dance he used to perform with the Pentangle!
As Mary G, says, John Martyn and Hamish Imlach both performed in The Glen at The Antares Memorial Concert, an evening that will take quite some beating. Apart from the music, there was a surreal moment where a dead sheep wrapped in binliners was raffled while JM cradled it in his arms, and Hamish crooned an impromptu blues about the sheep which had a call and response which John then joined in with!
Here's a link to Iain McGeachy's MySpace site (this is the proper one - any that say "John Martyn" are just fan sites or impersonators)

PS I've said for years that he should be in the Picture House!
