I was in the opening act for a blues festival, way down the bill, where Rory was at the top.

His band soundchecked first, he was on a delayed flight and just wanted to check everything so he arrived unannounced on stage with us during Key to the Highway, soundchecking about an hour before start time. He joined in and even made my lead lines sound better.

Afterwards, we had a lovely chat - such a humble man, no airs, genuinely keen on the music.

Then we went on as opening act, did Key to the Highway as the closer again and Rory walked on, grinning like a Cheshire Cat, to take the first solo, leaving me the second.

A truly cherished memory.

If you like the electric stuff, too, there's a box set "Let's Go To Work" which has all the four live albums on - I've just replaced my old vinyl.
