Just months before his death at the age of 77, Dad's Army star Ian Lavender revealed his cast's secrets with him to his grave

Dad's Army star Ian Lavender revealed he would take his cast members' secrets to his grave just months before his death at the age of 77.

News of the actor's death was announced on Dad's Army's official social media account on Monday as they paid tribute to the sitcom's final actor.

Lavender, best known as young Private Pike, was cast in the classic comedy series in 1968 at the age of 22.

And last January, Lavender said that the show's legendary cast members were so close that they shared secrets with each other that they “never told their wives.”

He admitted that he once promised co-star John Laurie (who played Private James Frazer) that he would never reveal the secrets they shared.

Lavender told the We Have Ways of Making You Talk podcast: “I spoke to John.” [Laurie] for so many hours. He said, “I told you things that I never told my wife or daughter.” “You have to promise me that you won't tell anyone yourself.”

He then gushed about his co-stars, recalling that filming for ten weeks every year was “great fun” with “wonderful people who became great friends.”

Lavender also revealed that the cast was shocked by the series' success after the first season initially failed to find an audience.

The post announcing his death said: “We are deeply saddened by the passing of the wonderful Ian Lavender.”

“In what truly marks the end of an era, Ian was the last surviving member of the main cast of Dad's Army.”

Lavender, who was born in Birmingham in 1946, was married twice. His first wife was actress Suzanne Kerchiss. The marriage lasted from 1967 to 1976, and the couple had two sons, Dan and Sam.

From then on he lived happily with American-born Miki Hardy. The couple married in 1993 after 16 years together after Lavender was diagnosed and successfully treated for bladder cancer. He also survived a heart attack.

Outside of acting, he was a keen supporter of Aston Villa Football Club and chose a burgundy and blue scarf as part of Pike's wardrobe.

Lavender had just graduated from drama school and had only made one television appearance when he was cast in Dad's Army, unlike the rest of the cast who were comic veterans.

During his six-month stint at Canterbury Rep he was earning £9 a week when someone came up to him and said he looked stupid enough to play Pike.

“I was a complete beginner and suddenly found myself joining probably the most experienced team of character actors in Britain,” he said.

“I was shocked to suddenly find myself surrounded by so many great actors. When the moment came for me to say something, Pike's strange voice came out in a moment of panic.

“Since then, at the start of every new series, it's been a hell of a job to conjure it up again.

“But Private Pike took me out of obscurity and onto television.” I would never have done that if I hadn't learned to say, “Ooh Captain Mainwaring, my mother said that even if the Germans come, I can't catch a cold.” “

The acting gig was only meant to last eight weeks – but the show's phenomenal success meant it lasted for the best part of a decade.

The film, which ran from 1968 to 1977 and attracted 18 million viewers, made Lavender a household name.

As Pike, Lavender was a comedic henchman in the series and was frequently called a “stupid boy” by the troop's captain, Mainwairing, played by Arthur Lowe, although the other members of the reserve army behaved more kindly towards him.

Lavender was key to one of Dad's Army's funniest moments when he performed a song calling Hitler an “idiot” in front of the German forces.

The Nazi captain says his name will also be on a list of people he will take revenge on. When asked what it is, Captain Mainwaring insists, “Don't tell him, Pike,” accidentally revealing his name.

His bumbling soldier role in the Home Guard comedy earned him fan mail from all over Britain – especially from women who wanted to mother him.

“I get letters from schoolgirls and middle-aged ladies who want to mother me. “I miss ladies my age,” he once joked.

Lavender's closest friend and mentor in the cast was Scottish actor John Laurie, who played the gruff undertaker Frazer.

Off-screen, the two often chatted and told each other jokes, a skill Lavender learned from Laurie.

“If I could pick one member of the cast to survive, it would be John,” Lavender told the Telegraph in 2018.

“Actually, I loved him. “He was naughty, he was mischievous, and he suffered no fools.”

In hindsight, Lavender suspected that the role of Pike had limited his career, once telling The Independent: “I was definitely typecast, but nobody expects you to make up that character.”

“People don’t want Frank Pike, but they expect you to be funny.”

After years of working in the series' fictional filming location, Wilmington on Sea, he made guest appearances in many television series and also appeared on stage. He appeared with Dustin Hoffman in The Merchant of Venice and also appeared in Sister Act: The Musical.

Outside of Dads Army, his biggest on-screen impact was as Derek Harkinson in EastEnders from 2001 to 2005 and again from 2016 to 2017. Derek was initially the boyfriend of Christian (John Partridge) and became close friends with the matriarch of the series, Pauline Fowler (Wendy Craig).
