I found a website with Jan's history, containing these label scans:
I just found a website on Jan Bradley's history, which has theses scans, and the rest of her discography of her recordings and songs written. I have the Prism Paulette record, but only on white DJ issue, and although I've seen several WDJ's, I've never seen a store stocker before. I don't believe the other 3 were ever released commercially, as I lived in Chicago in 1963 and 1964, when they were released, and looked regularly through thousands of records each week from their release through 1966, and part of each year from 1967-70, and I never saw them, and I never saw them in friends and other local collectors' collections. I didn't know that Don Talty released anything else by Jan on Jim Kirchstein's Night Owl Records. I would have guessed that after seeing that Kirchstein had no distribution for Soul and R&B records, and that all their local sales of "Behind The Curtains" were made through Talty's and Curtis Mayfield's connections in Chicago and Milwaukee, they would have decided to have them pressed and distributed by a label with decent distribution, like they did with Jan's "Christmas Time, making a deal with Stacey Records, or placing Paulette with Prism (not much better distribution than Cuca). But, maybe Talty just went to Krichstein because the latter let them record in his studio for free, just so he could get the pressing job (as was his usual deal)? - and they let the label remain "Night Owl" because Jan's "Behind The Curtains" was released on that label?
Chuck was Chuck Tillman, the leader of a Jazz Combo and, earlier, a Jazz Band. So, it may not be a duet, but just Tillman's Combo (Trio or quartet) backing up Jan's singing. The Royal Chessmen were a Chicago Mexican Soul Band (Lowrider style ballads and regular Soul uptempo sides). The Chapter sang Garage in a slightly (marginal) soulful style - so that record was on the right label, as almost every Night Owl release was Garage bands, other than Jan's 2 releases, and one or two weak Pop groups and single artists. I can't imagine why Kirchstein chose to release Jan on Night Owl, when he released his R&B and White Doo Wop mainly on his Sara Records subsidiary, and Cuca was mainly Polka music and C&W, with some MOR Pop, and a couple R&B/Soul (Birdlegs & Pauline, Harvey Scales & 7 Sounds, and Betty Moore (AKA Moorer). Maybe Jan and Talty liked the owl face label icon so much they demanded that label?
