It's interesting to consider what it is that makes a sad song, though.
There are plenty of ballads and broadsides with the most tear-jerking maerial, yet there's a 'factor X' that a real hair-tingler needs.
Shoot me down if I'm being over-imaginative, but I've ofen found that the most arresting songs, in terms of that lump-in-the-throat, dewy-eyed reaction, are those that are like the old church hymns.
I don't know whether it's an atavistic thing harking back to the days when religion was hammered into us to instill a mixture of terror and bewilderment, or whether it's that the Almighty managed to get some tunes back from the Devil, but I still find a classic Anglican evensong uplifting, even though my original faith is long gone. Perhaps that's why I always get very emotional with that wonderful song that Coope Boyes and Simpson do so well, 'Only Remembered'.
Yrs, an incorrigibly sentimental old fart.
