I love the tune collected by Vaughan Williams for Bramble Briar (aka Bruton Town) in the Penguin Book of English Folk Songs.

But I've never heard anyone sing that tune, though it's been recorded famously loads of times with a different, minor key melody (e.g. Sandy Denny, Pentangle, Martin Carthy, Fotheringay and others).

Are there any recorded versions with the tune as given in the Penguin book?
