Perhaps, but I don't believe him when he says why they were continuing on. From what I know of the band, have seen, plus his actions tell me this is a shameless cash grab. And it reeks of greed. Again, that's just my observation. I stand by it.
Speaking of money, I would bet a good sum that it wasn't just Deacon that made them continue. If Deacon had said no, Don would have tried to move on with another singer and see how fans would react. The buck didn't stop with Deacon, IMO.
Maybe he's not a pathological liar, but I think he fibs from time to time.
