I did attend an acoustic CSN show in 1991. There was absolutely NO political pontificating onstage insofar as criticism of Clinton goes...just some pleas that people support some sort of food charity. Then again, I may have missed some of what was said...the music was putting me under.
Clinton was a governor in 1991. Perhaps that would explain why there was no criticism of him.
Thanks for the correction on the paleo-rocksters. I used to know these things better but the mind gets a bit cloudy as the beard grows.
