I have a book from the mid-90s (called "To the Limit") which has a quote from Randy that he thinks of Felder and Walsh as "traitors" because he expected them to leave at the same time as him to form a new group. It didn't sound lke they had remained friends throughout, but possibly they reconnected after Felder was fired.

In Bernie's mail to Lefsetz, he said he's still in touch with Randy and Don Felder.
