I seen CSN 3 times, I was dating my wife for the 3rd time and was bragging them up to her, she was an A.M radio girls at that time. Crosby just got out of rehab for coke. When someone would whistle, he'd stop and start screaming like a mad man at the audience. Didn't take long til he walked off, while the audience was chanting "give him a line give him a line".
