Wade AND the Morris Brothers always claimed they were playin' 'bluegrass' music long before Monroe (with Flatt and Scruggs). They weren't.
The instrumentation was right, but the tempos were much slower and the keys much lower. Nope....for what WE call Bluegrass, you have to go to that magic night on the Opry.
Besides Wade has always been a Two finger picker (a great one) and I think MOST grass nurds agree that the banjo has to be played in three finger style.
Rhere's more evidence for Snuffy Jenkins band but it TOO was "old time" not bluegrass.
