I would suppose that after the announcement that Liam was going to released some new music, his back catalogue would have some exposure. But since I dont track the charts I cant say it was or wasnt that way.
The Beady Eye albums are sold out on vinyl and the few ones still available became quite expensive (that wasn't the case before 'As you were'). But that's just an effect from a customer's view. I doubt that Sony or the members generated mentionable additional income (the advances probably haven't recouped anyway)
