...”later came to find out Don Henley was a rabid liberal...”
That’s what did it for me, too, re the Eagles. IIRC, The Eagles were to play for an event for big lib politician Alan Cranston. One of the members, (Felder?), made a negative comment about it or something similar. Henley immediately flew into a rage and the band member was outta there. Henley is the worst; I guess Frey is about as bad.
I think this story was told in a TV documentary covering their most recent reunion concert, maybe 3-5 years ago.
It was Glenn Frey that threatened Felder for disrespecting Cranston. He came across like a real dick in that documentary. Made Henley look open minded.
