As far as I am aware, there is little available of his Sons of the Pioneers, which included fine musicians like Homer Sherrill, Zeke Morris, Clyde Moody and others, at least not on the better-known reissue labels - perhaps a few tracks scattered across anthologies. Old Homestead - its site appears to have disappeared from the Net; has the label ceased? - has/had a couple of what it refers to as 'double play' sets, albeit they are single CDs, devoted to Wade: 'Best Sacred Songs' and 'From the Maple on the Hill'. I have the latter [OHCD 4000] which is a compilation of recordings made at a number of sessions in the early 1970s with an assortment of oldtimey and bluegrass musicians, including Red Rector. Wade was in his 70s at the time. I don't know, but I'd reckon the 'Sacred Songs' is from the same period or later. Elderly Instruments has both these available. 'Maple' is a pleasant enough compilation, but it certainly didn't inspire me to fork out for 'Sacred' as well. Maybe someone will put together a compilation of his late 30s and 40s material - now that would be worth having!
