“We wanted to do BB King’s Rock Me Baby, but we didn’t want to do the standard throwaway, so we created a new arrangement with some interesting twists.

“The music came first and the lyrics came later. We were sitting on the bus, and it occurred to me that we were no strangers to the use of the phrase ‘Have mercy.’ So I told the guys, ‘Let’s do it.’

“We did a couple of takes – the first one and the second for safety. Practice makes perfect, and we had been playing the musical side of things, Rock Me Baby, for months, so I just said, ‘Hey, let’s play it and we’ll sort out the rest later.’

“It’s got a good sound to it. We were using the Magnatone prototype. It’s a 50-watt, all-tube, hand-wired 2 x 12 combo. A killer-sounding piece, really just awesome.

“At some point, we have to switch the lyrics on this thing live. I’m thinking that by the time we hit New York, you could get either version. We’ll have to find out.”
