Wow, what an opportunity that was, to see such a vintage gem, made back in the day when few shows were recorded, let alone saved. That cheeky little Welsh lad was quite a character, wasn’t he? Thoroughly enjoyed this precious slice of history – and I mean that most sincerely.
I desperately need a recording of my dad Jimmy Murphy who was a. opera singer from Cork played un the very early days. can anyone help.
I’m afraid you must prepare yourself for disappointment. It is vanishingly unlikely that any material has survived this long. Film was bulky and storage cost a lot of money; videotape was very expensive and was therefore reused (recorded over). If footage had no reuse or resale valuem then there’s a 99.99% chance it was junked.
The ABC Weekend film archive (aside from entertainment programmes) has passed through very many hands over the years but much of it currently resides with British Pathé. They have digitised a selection of what they have and put it online at https://www.britishpathe.com/ but they are very unlikely to be able to perform a search of their archives to see if they have the particular feature in question, especially since your request is so vague – it’s economically prohibitive to do so. Sorry.
