Ray, is this the one you're looking for? I've always known it as

WHOEVER INVENTED FISH FINGERS
(Leon Rosselson)

Whoever invented fish fingers ought to be crucified
Skinned, mashed and boxed into uniform blocks
Then covered with breadcrumbs from collar to socks
Then frozen and finally fried
For who would do that to a fish finning its way through the sea
Colours in harmony, perfectly poised, riding his flying trapeze

             Progress is all very well
             But not when it chops up our dreams
             And it's hard to feel at ease in a world
             Where nothing is quite what it seems

Whoever invented BILD-Zeitung ought to be cut down to size
Pulped, then reduced to a horrible juice
And flattened and dried until ready for use
Then covered with newsprint - and lies
For who would do that to a tree lifting its head to the skies
Rooted in centuries, telling tall tales and breathing a green lullaby

             Progress is all very well
             But not when it chops down our dreams
             And it's hard to feel at ease in a world
             Where nothing is quite what it seems

Whoever invented South African policemen ought to be licked into shape
Toughened and trained till the body's a cane
Till the arms are a chain, till the nerves feel no pain
Till obedience rules and encircles the brain
With walls - so he'll never escape
For who would do that to a child jumping with joy and desire
Floating in fantasy, drowning in dreams, brimming with fun and with fire

             Progress is all very well
             But not when it locks up our dreams
             And it's hard to feel at ease in a world
             Where nothing is quite what it seems
             What it seems
             Where nothing is quite what it seems


Iain MacKintosh used to sing this version (but never recorded it), so the lyrics are probably not quite what LR sings himself. 'BILD-Zeitung' is a German 'red-top' newspaper comparable to The Sun.

Hope this helps. Any other bits and pieces you can remember from that tape? We might still work out which one it was!
