They were a duo in Chicago in the 60's. Did a bunch of Oscar Brown Jr. songs. Recorded for Argo Records I think. Some song titles from them: "Bid 'Em In", "Signifyin' Monkey", "Rollin' Mill Done Burned Down". Their names are Roy Inman and Ira Rogers. This was 60's RAP---way before the craze for that. But RAP has long been a part of Afro-American life. Oscar Brown popularized a rap style in his compositions.Hope this might help.If you get to Rockford Il. check out TOAD HALL at 2106 Broadway.(phone is 815-226-1259)You might be able to check by phone & buy by mail. It"s a used book and used record store. Pricey but they'll have 'em I'd bet.Great stock. Good folks there. I found that place long ago when doing a gig with Jim Kweskin at Charlotte's Web, a good old club in Rockford (long gone). It was Kweskin that turned me on to the place.He'd go there searching out old 78 rpm records. Art Thieme
