Thanks for that titbit, Jim.
Here's an update (might jog somebody's memory) - got 2 verses now.....
My granny died the other day, it filled my heart with care
'Cos grannies are quite hard to get - and she's 1 of a matching pair.
The awful pain that my heart felt it made me feel quite flat
Until I found that in her will she'd left me her old felt hat.
And I've never felt an old felt hat like that felt hat felt.
Never felt an old felt hat like that.
I've felt some good felt hats and I've felt some bad felt hats
But I've never felt an old felt hat like that felt hat.
While riding my bike the other day downhill to the sewage farm
An accident befell me but my hat saved me from harm.
I hit a stone, sailed o'er the bridge and might well have been drowned
But my felt hat showed rescuers the spot where I went down.
There's at least 1 or perhaps 2 more verses missing.
