How much do input you honestly think Mike Harding had into his playlist?

When I asked if MH would play our album on his show he asked me to send him a copy, which I did. That he didn't play it I took in good grace & as a matter of personal taste - plenty of other stations did, from Bob's Folk Show to the Late Junction on Radio 3, so I'm in no way complaining here. Every respect for MH, it seems to me that he played pretty much what he liked to play which is exactly as it ought to be. And I doubt Sproaty Smith & Elle Osbourne are on any official play list, though I'd love to be told I was mistaken!
