Nash wrote this about his fellow CSN&Y bandmate David Crosby, who he's known for 50 years.
In 2016, he told FaceCulture
that he wrote the song just after deciding he'd never work with CSN or CSN&Y again. He wouldn't go into great detail, but made clear he had no desire to talk to Crosby ever again and that he thinks Crosby "is not a very great person."
Nash added that Crosby tore the heart of the band "in the space of a few months." The one thing he makes clear is that, whatever happened, it started with Crosby publicly putting down Daryl Hannah shortly after she started dating CSN&Y bandmate Neil Young.
