Just came across this from a few months ago. Nice long interview with JC in a cheerful mood, with a fair bit of chat about the early days. No wild revelations but some nice little snippets

There are plenty of great podcasts featuring him, and you can find most in this playlist:https://open.spotify.com/playlist/3ZB9H6uzWMb7HvQ2N0Hudy?si=DTkG1wsERaajQMiM-4lSEQ
Some podcasts feature other people as well, so you might have to fast forward to find JC's appearances. Nevertheless, he's in there.
Good new interview here, halfway of a promo of the album and the forever pending book (which he says has now probably changed title...):
