Bryan used to be the host of the Frontline Records podcast before an illness and he turned it over to Les. If you go back and find some of the old podcasts they are pretty cool and Bryan is very entertaining. I think he was talking about the name "D.A.S" and picked it so their albums would be near Daniel Amos. He was back on a recent podcast, not as host but as a special guest and it was fun listening to him and Les talk. They played some D.A.S on the show.
Another interesting fact was that Bryan was a stunt double for John Candy (no kidding!).
