As for the whole "How Come It" / "Rock It" single (which I lucked into at a garage 7 or 8 years back).... I don't care much for "Rock It", though "How Come It" is a fun song.
He was not proud of some the work he did for Starnes and Dailey there at the start. He was just a hungry artist doing whatever he could for a few bucks. A fan once approached George with a copy of that 45 for him to sign... George basically called it shit and snapped it in half. I once saw an interview done with Ralph Emery on the the Nashville Network and Ralph mentioned they had found an interesting little song George had cut as Thumper and proceeded to play either "Rock It" or "How Come It". George almost slid under the table out of embarrassment.
"Maybe Little Baby" is the best rockabilly he cut by a mile.
He actually sounds purpose-driven... in the pocket and waiting to get into some gal's pants.
Perhaps Brown will be drawn out and share some thoughts.
