Why isn't Baird Jones' memorial party being held at Webster Hall, where he was the "art curator" and rumored to have been paid $500 everytime he got Page Six to mention it? Good question. Better question: Why is tomorrow's event being held at The Plumm, a club he tried to have closed and whose owner, Noel Ashman, Jones described as a "crook" whose "middle name is 'fraud'"? Since he couldn't publicly bash The Plumm, as he needed inside access to do his "reporting," Jones privately corresponded with alleged Plumm vandal Ivy Supersonic; the two of them were well aware of Ashman's tendency to stiff the very club promoters responsible for filling his venue with maybe-of-age models. Ashman denies the charge. [NYM]
