Yeah, that's what I've read also. He has a bit of a monolouge prior to a song on the album, where he basically says to the audience if he drank half as much as they thought he did, he'd be dead! Joe E Louis is the quote's author according to Dean on the album. Although he does reference it in the context that he and Joe were "swimming" in his den one night.....

It's actually pretty humorous. I know that he played that reputation up quite a bit unlike Frank and some of the others who really lived it. Thanks for the reply.
