Maybe we could ask Rusty, he seems to make himself accessible to the fans. Heck, maybe we'll even get to read his long-promised autobiography soon!
I'm not so sure that signing to Apple would have been the best thing for the band. It didn't seem to do much for James Taylor or Jackie Lomax.
Being an uptight nerdy sort, I would like to point out that there's a slight time discrepancy between the Poco Angelfire page saying Pogo's debut at the Troub was in October and Rusty saying November. Also, in Richie Furay's autobiography he said he was aware that people thought RFD stood for Richie Furay's Dream, but it was really just an homage to the "Mayberry RFD" tv show.
Going to take my medication now...
