Jarv was on this BBC World Service programme, Music Life the other day. They get 4 musicians to talk together about aspects of their lives as musicians, with one of them being the "host" who has to do the intros and guide the conversation along, John Grant in this episode. He doesn't say anything that I found especially new or earth-shattering, but I always find it really nice to listen to him talking when he is being less formal and more chatty. I don't know if this is accessible or not outside the UK on BBC Sounds, but as it's the World Service, you would hope so. If not, I have the mp3 of the podcast I could upload somewhere.

As he's also on Christmas Catchphrase (https://baritalia.activeboard.com/t66105621/jarvis-on-festive-tv/), this could almost count as a promotional campaign??
