I stand corrected. I've just listened to the embedded tracks at http://www.myspace.com/walkaboutsverse .
I don't think I've heard 'When I survey the Wondrous Cross' quite so mangled. A monotonous and flat rendition brightened only the the Stylophone accompaniment. To misquote the great Rolf Harris, "Can you hear what it is yet?".
Then there's what sounds like a pisspoor pastiche of Henry Lawson (complete with whistling and humming!). Then some poetry, which I quickly passed over.
I did catch a snatch of 'Cob-a-Coaling', which sounds bizarre when sung in an Aussie accent trying sound like a Yorkshireman! Priceless - the best track of the lot for laughs.
I'm afraid I didn't listen to all of it, however, as I was losing the will to live...
Suffice to say, I don't think Eliza C (or her mum) has anything to worry about.
