“Buddy Guy did perhaps the definitive version of this song, which was written by Walter Jacobs. But I put a new riff on it - I like doing that occasionally to old songs, just to put my own stamp on them.

“I cut it the same day I did The Meaning Of The Blues, so I used the old Strat again. Actually, I wound up breaking the tremolo bar clean out of its cavity - that’s always fun. [laughs] That can happen with an old Strat: You’re getting wild with the whammy bar, going all nuts, and suddenly you feel no resistance at all. That’s when you go, ‘Oops. I know what I just did…’

“I used a George Tripp-modified Crybaby wah pedal. George has built me, like, six or seven wahs - the guy’s incredible. I don’t use the effect a lot, but when I do, I want people to know it. I go for a big sweep, almost like what you used to get with those Morley Power Wahs - all that tremendous high end. It’s huge and dramatic…which is the idea, really.”
