There are so many. Sometimes on music night we'll get into the saddest mode you can imagine and at some point someone will order a round of "the happiest song you know". Otherwise we'd all slit our wrists...

I agree that sometimes a tune is just as sad as lyrics; Campbell's Farewell to Red Gap' and 'Lament for the Reverend Archie Beaton' come to mind.

The songs I think of as MOST sad are those that speeak of human frailties. For instance, 'The Fields Have Turned Brown' which has him roaming the world for years secure in the knowledge that when he went home again they'd be there waiting- and when he does, they have been dead for years...

'Kilkelly' is heartbreaking. 'No Man's Land' as sung by Collette Costa leaves me snivelling.
