It sounds to me as if a mentally ill man is being forced to do something against his will.
I have not been deeply into the BBs until the last few years, so I don't know the complete backstory of events with Landy or the SI album.
If you are right about this, that's very unfortunate.
I know one thing: I saw the "Summer of Love" video for the first time tonight and Brian definitely looks unhappy to me in that one. It seems strange he would even be in that video since he apparently didn't have anything to do with the song.
I think I need to read more about Brian's history to really comment intelligently on this.
