With or without troll intent in the OP, I find the discussion interesting.

I tend to see logic in BountyHound's retelling of Tim Hart's wisdom. My own personal preference is for light accompaniment with acoustic instruments, but I can see validity in the use-what's-to-hand thing.

Certainly it seems unlikely that the traditional songs' writers lost sleep worrying that instruments of the future may somehow ruin their work.

As I say, I personally draw the line according to the powercut-in-a-field test. If you can play it in a powercut, or in the middle of a field, then it may just be ok.

This mostly eliminates electric guitars, synths and DJ decks... ;-)
