"Happens to all of us y'know... being born."

Between 1970 and 1975 Peter Sellers made films which mostly fell flat commercially, and some of which didn't even get released, but there was the odd little gem and The Optimists of Nine Elms, directed by Anthony Simmons and based on his novel, is perhaps one of Sellers' most personal films. The task of embodying Sam, a washed-up old music hall entertainer, prompted Sellers to channel both his father and his great hero Dan Leno and look back to his youth, trailing around theatre after theatre with his parents, soaking up the patter and the hoary old routines, the songs and the stagecraft.

Joining Tyler this week is writer and presenter Bob Fischer to talk about the film, released exactly 50 years ago. It centres around Sam, who is reluctantly befriended by two children seeking a distraction from boredom. With their parents both too busy working to give the children much in the way of attention, by contrast Sam has all the time in the world to keep the children occupied and entertained in his own slightly irascible fashion. The three, along with Sam's beloved dog Bella, form such an unusual bond that occasionally you are left wondering who are the children and who is the adult.

Shot through with some great songs and a terrific score by George Martin, plus really great performances by the young actors and Sellers, not to mention the ever reliable and slightly shifty David Daker, The Optimists of Nine Elms is well worth a watch - a sweetly melancholy tip of the hat to an entertainment tradition that had all but passed from memory, as well as showing the last knockings of London's slum culture and the general post-war malaise.

As well as talking about the film Bob & Tyler's chat includes a whole bunch of conversational diversions, taking in the Simon Park Orchestra; Behind the Fridge; Tucker's Luck; Bowie; Boon; Cheggers AKA 'Passion in Pants'; The Ladykillers; The Ballad of Sam Hall; Fulham FC; Coronation Street and much much more!
