Actor/director Gabriel Byrne, cultural ambassador for Ireland, was the guest of honor at Irish Amb. Michael Collins' home Monday night. "John Lennon," said Byrne, "reminded us how the imagination can interpret and reshape the world around us." Lennon was the grandson of Irish immigrants to Liverpool. Byrne, who discussed his role in the Imagine Ireland arts project, also dished on being one of People magazine's Sexist Men Alive.
