Discovered this in the Tones Hi-Fi Songbook:

What shall we do with a floor-laid cable

What shall we do with a floor-laid cable

What shall we do with a floor-laid cable

To enhance its sounding?

Hoor-ray and up she rises

Hoor-ray and up she rises

Hoor-ray and up she rises

Improvement resounding!

Raise 'em from the floor to counter static

Differences found will be dramatic

Really big improvement automatic

Ignore sceptics' hounding

Hoor-ray and up she rises

Hoor-ray and such surprises

Hoor-ray we know who's wisest

Sceptics sure confounding!
