Porridge - Season 1 Episode 6

Fletch's radio station is a great success, his relationship with elderly cell-mate Joe less so, as is news of his appeal and in frustration he plays provocative songs on air. To solve one of the problems Joe is given a single cell but Fletch's relief is short-lived when he is forced to share with an even more annoying inmate and he hears bad news about Joe – realizing that the old man was not so bad after all.
