I,d never heard of Robert Jenkins and he was certainly credited with playing on this tune.I cant even find very much about the man,so its difficult to compare his playing with Little Walter.Heres an excerpt I found online published on Big Road Blues recently. " The Jenkins sides were issued on Parkway, one of those small Chicago postwar blues labels that developed a legendary reputation based on a handful of recorded sides. In all, the label was in business for little more than 4 months and produced only 23 recordings, of which 14 were released at the timeāfour by the Baby Face Leroy Trio, four by the Little Walter Trio, two by Memphis Minnie, two by Sunnyland Slim, and two by harmonica-blowing Robert Jenkins. There's a fair bit bit of speculation that the harmonica player on these sides might be Little Walter.I'm no harp expert so I'll leave it up to the listener to decide"
Here is an unissued Parkway recording of The Little Walter Trio from 1950.
