Sonny Boy Williamson "III"

Not a typo. As part of Dennis Gruenling's Zoom Q&A yesterday with Steve Guyger, Guyger mentioned "Sonny Boy Williamson III," the 1950s harpist and vocalist Louisiana-born Edward William Johnson, who appeared in shows and on recordings as "Jeff Williamson," "Golden Boy Williamson," "Golden Boy," and on some labels simply as "Sonny Boy Williamson." His recording of "Mailman, Mailman," which Dennis played, is great. Anyone have any idea where one might find his recordings on CD?
