Getting a copy of/downloading a TV program

This is a long shot but I am after a copy of a Panorama program called Old, Drunk and Disorderly that was aired in 2012 on BBC.

We had this on the sky planner but it has disappeared, my other half is gutted as the program has a personal value to her.

Does anyone know of anyway to get hold of this? I would be forever grateful.
