Not directly (and don't forget that it's Nic, not Nick) but Mike Raven had something useful to say about the tuning used. ( http://www.freefolk.com/nicjones.htm ):

"I asked Nic which tuning he used for his arrangement of Seven Yellow Gypsies. He was not quite sure but thinks it was D G D G C D  (G tuning with the 2nd string up to C)."

There's a start at least.
