Sitting in front of a computer screen singing...Really sounds sad - but it's what we do on the Mudcat when we want to share a song with someone far away? (Won't be long and we'll do it in the singing bar in the virtual reality Mudcat Tavern, I suppose.)
("Sitting in front of this screen I am singing
singing a song that you never have heard.
Over the ocean my words now are winging
Telling the tale of what has occurred..." That's a song I haven't written yet, but I might well.)
Work songs as a way of helping us combine the way we are using our muscles - sure, I can't see much future for that, except as relics and fun and history. But songs about the work we are doing, no reason there shouldn't be plenty of new ones for ever.
There have been plenty of good songs about teaching, for example. Or lorry driving. Working in offices doesn't seem to have produced many - though Chesterton wrote a great song about shipwrecked Bankers once:
There's a run upon the Bank
For the Manager's a crank,
and the Secretary drank,
and the Upper Tooting Bank
Turns to bay!
Stand close: there is a run
On the Bank. Of our ship, our royal one,
let the ringing legend run,
that she fired with every gun
Ere she sank.
