Firefighters serenade Judi Dench in London

LONDON (AP) — Judi Dench has been serenaded by firefighters as she arrived for the London premiere of her latest film.

Dench walked the red carpet in Leicester Square Wednesday for the London Film Festival screening of "Philomena."

The movie tells the true story of Irishwoman Philomena Lee's quest to track down the son she was forced to give up for adoption 50 years earlier.

Members of the Fire Brigades Union, drinking at a pub after a protest march against pension cuts, spotted the 78-year-old star, chanted "We love you Judi" and broke into a rendition of Beatles song "Hey Jude."

The Stephen Frears-directed film also stars Steve Coogan as Martin Sixsmith, a journalist who helped Lee in her search and wrote a book about her story.
