The Wikipedia page on the Dixie Dregs is actually pretty good in terms of the factual history of the band:
Many of us have our own sites in various states of maintenance, Steve’s being the most up to date. In case you missed them, here are the links:
Allen and Steve Davidowski do not have sites, but they will post here, or on TheDixieDregs Facebook page as we move along.
Thanks! Andy West
