Henry Gray (official wiki AMG) has been playing professionally for almost 70 years -- he's worked for Bo Diddley, Howlin' Wolf, Jimmy Reed, Sonny Boy Williamson, Taj Mahal and so on. He was born in Louisiana, like so many of the best performers of Stag, and now lives there again.
This is a great, rockin electric blues version of Stag -- one of the few in my collection which include both fiddle and harmonica, come to think of it. Since Gray is a pianist by trade, the piano is nice and high in the mix -- lots of fun.
This is a live version from 1999, and five years later he'd record the song again; both albums include his cover of "Sweet Home Chicago," among others.
