PBS’s Memphis Soul special from the White House just concluded. The performers were all top notch. I was impressed that Justin Timberlake did a nice job on “Dock of the Bay.” I just wish someone would tell him to stop singing falsetto and just sing. It’s a gimmick, and it’s not working. Sam Moore was the star of the night, bringing the house down on “When Something is Wrong with My Baby.” But Mavis Staples had her usual ebullient energy on “I’ll Take You There” and Cyndi Lauper was fine on “Try a Little Tenderness.” Eddie Floyd hit just the right notes on his solo hit “Knock on Wood.” Queen Latifah was soulful on “I Can’t Stand the Rain” but they could have gotten Ann Peebles to come in from Memphis to sing her hit. And why did an “American Idol” reject sing “When a Man Loves a Woman” when Percy Sledge is alive and well? Anyway: All in all, a very satisfying evening which will be trimmed up for April 16th. The audience was mostly PBS types and political drones, no celebs per se. But the real celebs were on stage, and that’s the most important thing.
