Sparrows Can't Sing is adapted from a Theatre Workshop play by Stephen "Blakey" Lewis; Lewis himself plays a milder prototype of his celebrated jobsworth. There isn't a huge amount of plot - Barbara Windsor's husband is coming back home after a long absence, unaware she has shacked up with someone else - but this leisurely film is so rich in atmosphere, character and comic moments that you never miss the impetus of a more tightly plotted storyline. And I don't know how it felt when first released, but watching today the portrayal of a community where everyone is interconnected makes it seem like a world away, though the rubble of demolished houses replaced by new high rise blocks make it clear that London was already in a state of transition to greater impersonality. Oh, and the filming at the end takes place in an actual pub - owned by the Krays.
