Regarding Mr. Benson in this song, he was a music attorney in Memphis. He and his wife spent part of the summer on the Dead's farm in Calif. He had a fling with one of the Dead's women. This song is about that -- he was a ladies' man. I know the meaning because he was one of my dearest friends, and he told me about it himself -- and how strange it was/is to hear those lyrics about blowing him straight to hell. He was not a drug dealer.
