Actually, it was the Liam Clancy obit.

I really can't place the "Pat O'Brien" to whom Guest: TJ in San Diego referred. The only "Hollywood Pat O'Brien" that Google comes up with was an actor of Irish descent - and (as far as I can remember from the movies listed in Wiki) he wasn't a singer particularly. Oh well, it makes a good story, anyway, and complaining about it, considering the circumstances is, IHMO, inappropriate.
