Not directly...however...the depression it sent Welch into to be literally written out of history of a band he was a big part of when it was in its formative years...yeah..that is on Wenner’s hands. The 2 decades of depression...I’d say so.
I guess I don’t know the whole story. My memory is of Welch joining the band during it’s transition from a blues-based outfit to a more pop oriented sound. Bare Trees is a favorite album of mine from the 70s.
