I suspect this may be the same thing that was on Sirius XM, but the new Fleetwood Mac lineup were interviewed for the Rolling Stone Music Now podcast. Haven’t heard the whole thing but they tell the story of how this all happened. Unlike Sirius you don’t need a subscription, so check it out on whatever podcast app you like.
It is the same interview. Without a Sirius account, I was still able to download the Sirius XM app and listen to the interview under the Rolling Stone Music Now folder. I was surprised but I’m hoping other Sirius content is free.
The Rolling Stone interview was just posted as the Rolling Stone Music Now podcast which is available everywhere. Here is one link to hear the interview:
