Woody's influence was large and certainly used/felt/performed by even the commercial groups like the KT (e.g. "Pastures of Plenty" & "This Land" on Guard's final album with them) and tunes like Wildwood Flower on Reuben James in John Stewart's era with then. But Woody never hit it commercially like the pop folkies and mostly was regretably forced to listen to his songs performed by others. At least it got his name out there so he influenced the music but not really the big "boom" in folk music in the US in the late 50's and 60's.
