If - on the off chance that this interview was what it says it was - I kinda think they purposefully used a smaller radio station with not much publicity or credibility, just so it wasn't blown up as much. Putting it on BBC Radio 1 would have made it that much of a bigger deal, and I think this was more of a hit to the fans, if that makes sense. I highly highly doubt this will ever get confirmed, it wouldn't do shit. This is like an off-confirmation that can be disregarded later.
That’s the other possibility, that it was intentional and worked like the Simon Jones interview with words that can be easily walked away from and through a venue (like the Sun) that doesn’t get a lot of respect. And the purpose would be to give the story a bit more gas.
