Cover art for Farewell, Farewell lyrics by Fairport Convention

Surely this is just a downtrodden and deserted woman asking her abusive and wandering man whether he will ever do right by her and the kids. It's the way Sandy Denny (sadly missed) sings it that makes it sound so unearthly and mysterious - it doesn't sound at all the same when the current Fairports perform it, even though their version is also excellent.
