If you’ve ever fancied an intimate evening with sex comedy star Robin Askwith, now’s your chance. The Confessions of a Window Cleaner actor, is coming to the Cinema Museum with his ex-wife actress Linda Hayden to personally escort film fans on a trip down memory lane.

Film historian and ‘70s specialist Darrell Buxton is interviewing the duo at the Kennington museum. Robin and Linda have been friends for 50 years and have notched up some 50 films between them, from Baby Love (1968) and Cool it Carol (1970) to an eclectic mix of sex comedy, art house, horror, musical and the downright insane (see 1976’s Queen Kong).

Their television careers have been just as varied, with appearances in most of the top sitcoms of the 1970s, as well as drama series and playhouse productions. They’ve worked in theatres all over the world, often sharing a stage.

When I speak to Robin he’s kicking back in Devon at his girlfriend’s house; he lives in Malta and has recently been sailing around the Mediterranean. He’s also at the tail end of a solo UK tour, which began in the Cinema Museum many moons ago. “150 people showed up to that first show. This one is a peculiar one, which is what makes it interesting and slightly different,” he said. “Believe it or not, I get bored of talking about myself –I waffle on for an hour and a half in my solo shows, I have a theme, and I go off on tangents. But this show is quite structured with an interviewer,” he said. “We came up with the idea of me and Linda because we bicker, we argue, we were married for a long time, and she’s my closest friend. I’ve known her since I was 16 and she was 14.”

The two met as teens when Robin and his best friend were at school at Merchant Taylors’ and Linda was living in Middlesex. “I was at a posh public school, and we were rampant teenagers and used to look out of our window and watch Linda go to school,” Robin said. “I thought ‘she’s the best looking girl I’ve ever seen in my life.’ We were brought up in the same sort of environment, we knew of each other, then we really got to know each other in 1974 when we were both cast in Confessions of a Window Cleaner,” he continued. “She was cast before me. I was very experienced, I’d made a lot of films but she had a higher profile. She was the main female ingénue, and she was very hot in every sense of the word. I was still up and coming; she was considered a bit of a coup by Colombia to get at.”

“We didn’t become boyfriend and girlfriend until years later,” he said.

Confessions of a Window cleaner was a huge success, but Linda refused to sign a fixed contract. “She had a more serious career,” Robin said. “We worked together a lot, on Let’s Get Laid [1978], Confessions from a Holiday Camp [1977], Queen Kong [1976]. Real strange films!” he said. “And we worked a lot on stage. We did Run For Your Wife for a year in the West End, and went round the world on my world tour in the beginnings of the ‘80s; we had an absolutely great time, we were always friends.”

Linda’s been married to theatre producer Paul Elliot since 1988; the couple has two children together, whom Robin is Godfather to. “My girlfriends who’ve followed haven’t been as understanding,” he said.

Throughout the night at the Cinema Museum, host Darrell is going to show an “eclectic mix of film clips,” Robin revealed. “Linda made a lot of serious films like Baby Love, and the horror Something to Hide, and she has quite a following with those retrospective movies.”

He said this show is a one-off “mainly because Linda’s difficult to get hold of, if you’ll excuse the expression!”
