I think you're right, Moogmodule. The party thing wouldn't have made news if he were a true has-been.
Anyway, other signs of a possible true has-been-ism could be alcoholism, overly long hair, unshaven floor length beard, disheveled looking, raggedy clothing, shoes with holes in them (barefoot), obsessive-compulsive rituals, talking to self out loud and cussing, rotund girlfriend with missing front teeth, hanging around with Pete Best or appearing on his albums, etc. Yeah, I don't think Paul has any of those symptoms so far. Yes, I studied psych in college so I know whereof I speak!!
Yep, he's good. He's an is not a was, I humbly concede. Thank you, Moog!
