Yes, it can. It makes me so happy to know that the best organists are crappy singers. McDuff was bad too in the vox dept. But Groove really takes the cake!
The drummer I play with now in my organ trio is from Memphis and backed up Groove for a while. He said the first time he met Groove, Holmes was in the dressing room sprawled out in a chair, big as life, eating a tub full of fried chicken with the discarded bones surrounding him on the floor. Man....THAT'S the way to meet Groove Holmes.
Oh, I don't know. I reckon his vocal on "Polk salad Annie" is no worse than most of Jimmy Smith's. Neither was a vocalist. I much prefer to hear Holmes or Smith singing than Joey D. I can't remember McDuff singing; what album does he sing on? Earland could sing reasonably well. Lonnie is best of all, of course.
