Bad news about Peter Pan

I e-mailed BBC Radio 3 about where to buy or download "Peter Pan at the Players". Here's the reply from Bill Lloyd, a Radio 3 producer:

Sadly not. And owing to the rigorous rules of the American musicians' unions, we won't be able to repeat it either. So it was just a glorious one-off for the Peter Pan centenary. I hope you enjoyed it anyway.

So unless anyone recorded it, it's lost forever I'm afraid.
