The night after he shows his wife of three decades, Iolanda, a publicly good old time on Broadway, doesn't he turn out just as publicly Monday with youngish ex-secretary Kathy Benvin, mother of his latest kid, who was born last summer. Took her to a Manhattan screening of La Strada.

He blamed "negative critical appraisal" or lousy reviews of the show, which he produced in London.

Sources said that the actor just wasn't up to the Jule Styne tunes and that his attempt to do a Rex Harrison-like sing-speak wasn't working. He was replaced by understudy Steve Barton, who originated the role of Raoul in The Phantom of the Opera. Said Rees: "We all care about The Red Shoes too much to make a size 11 squeeze into a size 9." Or a 9 into an 11!

THE MAG TRADE
* Daryl James, editor in chief of the national hip-hop newspaper Rap Sheet, said it would accept no ads containing guns.
