Just to confuse things....
I have "You Ought to Know" on a Paul Gayten/Annie Laurie LP on the Swedish Route 66 label. It gives a location/date as New Orleans, late 1949, with this personnel:
Paul Gayten - piano & vocal; Wallace Davenport - t; Lee Allen - ts; Frank Campbell - as, bar; Jack Scott -g; George Pryor - b; Robert Green - d
This is a much more likely personnel for a New Orleans recording; I doubt those New York guys would have made the trip south. The tune is a nice, moody ballad with a good tenor solo. The whole album is excellent early New Orleans R & B.
The album has one track, "Goodnight Irene," with Mobley listed on tenor. Unfortunately, there's no tenor solo. I always chuckle at one line of "Broadway's on Fire": "That bebop is okay, but I've got to have some blues."
When Buster Brown recorded the same song in 1962, he changed the lyric to: "Rock n roll's all right, but I've got to have the blues."
