Sillerman trying to get CKX back

X-MAN SEQUEL? Speaking of Idol and the Post, the paper reports that Robert F.X. Sillerman, who left the CEO position of CKX in May to launch a takeover attempt, said yesterday that he plans to ask shareholders to sell him their stock for between $5.50 and $5.75 a share to gain a controlling stake. At the high end of the range, the offer values the company at $535 million. Sillerman's bid values CKX below a competing offer from his former partner and Idol creator Simon Fuller, whose offer earlier this year valued CKX at $600 million. Fuller has since dropped out of the bidding. (8/12a)
