Prison life comedy

Hi all,
I was on a transcontinental flight recently on Swiss Air and caught the tail-end of a British comedy about prison life - I'm sure it dated back to the 70's. Can anybody help me with the name of it? I don't remember ever seeing it here in Canada. Thanks

Porridge? https://www.comedy.co.uk/porridge/

Vince: Is this just so you can show off? You could have just said you were on a plane, you know.

Hi Vince. Were you pleased with the airline?

Hi all,
No, I was not trying to 'show off' - just setting the stage for how I came across seeing the show for the first time - we don't get all your shows 'on this side of the pond'. Yes, the airline was very good - food was better than average for an airline. And YES, Porridge IS the show I was looking for. Thanks all who replied.

Are you a French Canadian or a real one?
