I had the tune for this in my head, but I didn't know what it was called. A look in the DT came up with Anne Cooper Hewitt - a song that fits right in with the Song Challenge ethos!

Anyway, back to Rosie:

ROSIE THE SEEING-EYE PONY

I'm Rosie the seeing-eye pony
It seems I've found some kind of fame
TV pundits of intellect
And 'cats on the internet
Have heard of my calling and name

I'm Rosie the seeing-eye pony
A help to poor Cherry, who's blind
But it's not just my skills
That give people thrills
It's the red knickers on my behind

I'm Rosie the seeing-eye pony
I was potty-trained as a foal
But people don't trust me
And so they must dress me
A two-foot high pony so droll

I'm Rosie the seeing-eye pony
A horse well in front of the cart
I'm not dressed to thrill
And I'm not dressed to kill
For I'm really a nudist at heart

I'm Rosie the seeing-eye pony
'Just get these things off!' I would say
Next door there's a stallion
Who wears a medallion –
These ruddy things get in the way!
