Salim,
I feel it would be great, but my feelings do not get round the practicalities. I think that the BBC hold some sort of legal control over the Electric Proms and it would need negotiation, possibly of a legal nature, to release material.
I think it is possible that the televised programme might be shown again at some time. I looked at the listings section of the Sunday Times and noticed that the Maddy Prior concert is being shown again on BBC4 this Friday, albeit as part of a folk night with (another) repeat of Folk Brittania, together with an earlier Maddie Prior concert (no doubt including Gaudete, which will get us into a festive mood).
So I will keep watching the BBC4 footage for any more Electric Proms repeats, including Nitin's gig.
I entirely agree with you that Nitin's work should be brought to a larger audience - I keep banging on about it and dragging people off to his gigs!
