David Crosby: sperm donor to Melissa Etheridge, father figure to Drew Barrymore, and the black sheep of my beloved Crosby, Stills, Nash and Young. None of the band members will speak to David anymore. Not Stills, not Nash, and certainly not Young (David called Neil Young’s wife, THEE Daryl Hannah, a “purely poisonous predator”). So yeah, for an old hippy folk singer, 79-year-old David isn’t known for being super chill. So it’s not surprising that he pissed off people on Twitter last week. In response to a fan asking for his opinion on the late Eddie Van Halen, David tweeted, “Meh”. Uh oh.
