Big Daddy Rogers been around since at least the 80's. Bud Harper Gary Rushbrooke very late Wigan? Certainly early Stafford etc. AC Reed Guy Hennigan then George Sharp. Mickie Champion a well seasoned oldie. These were just good Northern to most I knew, everyone got on with it. Some grumbled as some always do. The R&B argument really took hold for me when the likes of Charles Sheffield, Ernie Washington and other records that sounded even earlier started getting spins.
Most are now accepted on the scene but there are still many who like there soul nice and smooth and not gritty or early. Ass someone said horses for courses. Most know what DJ plays what, if one is known for playing something you don't like avoid the club, go somewhere that will please you. Get on with it, life is too short.
