FAMILY STYLE: Apparently, there really is such a thing as an amicable Hollywood divorce. Ellen Barkin and Gabrielle Byrne officially split nine years ago, but they were yukking it up with their children, Romy and Jack, Wednesday night. The foursome were all smiles over a leisurely dinner at Keith McNally’s Morandi, sharing a few laughs and spoonfuls.

SASSOON THE HERO: Vidal Sassoon is known as a radical in the history of hair care, but now it seems his fighting spirit extended to antifascist politics. This week, the British hairdresser’s early years as a foot-soldier in a London antifascist movement, the 43 Group, founded in 1946 by Jewish ex-servicemen, will be revealed as part of a BBC Radio 4 documentary, “Archive House: A Rage in Dalston.” The program, to air on Saturday, describes the teenage Sassoon’s battles against Sir Oswald Mosley, leader of the British Union of Fascists, in East London after World War II. Sassoon, now 80, grew up in London’s East End and his day job at the time was trainee barber at a London salon. He describes going to work one morning after breaking up a pro-Mosley meeting: “I’ll never forget. I walked in and I had a hell of a bruise. It had been a difficult night, and a client said to me, ‘Good God, Vidal, what happened to your face?’ and I said, ‘Oh nothing, madam, I slipped on a hairpin.’” He added of his fellow 43 Group members: “I was 17, these were all ex-servicemen at least five or six years older than me, and many of them won medals. I was a private.” The 43 Group fought against Mosley and his cronies, breaking up their meetings with knives and razor blades, until 1950 when the group disbanded.
