Song of the day

I heard Bryn Terfel singing this jolly song at The Grange last week:

I chanced upon a big brown bear
a gruff old bear was he.
He basked content within his lair,
I looked at him, and he looked at me.
And all he said was "GRRR!" Ah me.
And all he said was "GRRR!"

That big brown bear just hugged his lair,
And blinked a twinkling eye.
He ne'er as much as moved a hair,
But scared to death was trembling I.
And all he said was "GRRR!" Oh My.
And all he said was "GRRR!"

I doubted his sublime intent,
and did not stay for proof;
my heels in flight were swiftly bent,
for I'm inclined to stay aloof,
when big brown bears say "GRRR!"
Oh my, Oh my,
Oh my, Oh my, Oh my.
When big brown bears say

"WOOF!"
