‘Michael Rosen talks to comedian Elis James about how to make language funny.’
Today’s programme is a very interesting and funny conversation about contrasting humour in Welsh and in English. Quite a lot here about how the two languages work differently in comedy and in everyday life. Recommended!
that sounds very interesting, thanks for posting 
Really enjoyed that!
yes me too, listened this morning
Darn - “Sorry, this episode is not currently available”
Edit: except apparently it really is, but at a different link: BBC Radio 4 - Word of Mouth, How to talk funny with Elis James
Great programme, could have listened to them talk three times as long!
And for those who want to keep it, note that it’s downloadable as a podcast.
