Further info from Joe Boyd's latest newsletter, sent earlier this evening:

The BBC filmed our recent Way To Blue tribute to Nick Drake's music and is broadcasting the concert this weekend. It features performances by Vashti Bunyan, Lisa Hannigan, Teddy Thompson, Robyn Hitchcock, Krystle Warren, Green Gartside, Scott Matthews, Harper Simon, Neil MacColl, Danny Thompson, Zoe Rahman and Kirsty Almeida - with Robert Kirby's and MD Kate St John's arrangements.

Below are UK broadcast times. Not available online I'm afraid, and no immediate dates for BBC America.

The Songs of Nick Drake: Way To Blue will tx on BBC Four this Friday (16th April) at 9pm.
