That's good - I was hunting around at the weekend and the only thing I could find was something that said there were no plans to show it at that time. Maybe the number of hits it has had on BBC Sounds has made them reconsider.
Looking around, it seems that there are no plans to broadcast this on the TV. I know they can't televise every one of the Proms but you would think it would be good to show special ones like this which are likely to broaden the interest of people who think the proms are just classical stuff.
