I can't see a catchup facility on O_G's link.
The programme will be shown on 4Seven again as follows:
0200 tomorrow (or tonight, depending upon how you see it!)
2000 Thursday
2000 Saturday
(4Seven is on channel 47 on Freeview, BT, TalkTalk & YouView. Channel 140 on Sky, 127 on Freesat, 195 on Virgin).
The programme was made from selected clips held by the North West Film Archive. You can view the
full collection here:
