Croz has always been the one of CS&N with the least money because his music wasn't sampled or used on soundtracks as much as Stills' (including his Buffalo Springfield stuff) or Nash's horrible-but-advertisement-friendly twee songs. And he has lots of kids.
The one relationship in CSN&Y which was a constant was Crosby & Nash - the latter was a self-appointed peacemaker/runner in the group. But Nash estrangef himself from Croz after those comments about Daryl Hannah.
