You're right of course, Kitty. It is jack halyard, otherwise known as John Warner. And he REALLY doesn't like Christmas, or being told he looks like Santa. He even wrote a song about it:

Beard Protest Song.

John Warner - 2 May 2004

I protest! Surely my hirsute features cannot be sufficient cause,
For all the kids in Sydney to call me "Santa Claus"

I don't look a bit like Santa Claus,
My verdict is official,
If the beard on me is all you see,
Then your look's too superficial,
There's Karl Marx and Henry Parkes,
With whom I could be compared,
But its plain to see that you can't see me,
If you just see the big, white beard.

We don't judge folks by the slant of their eyes,
Nor yet the colour of their skin,
You don't match a fella like Nelson Mandela,
With the likes of Idi Amin.
Well I'm the same, I resent the game,
Folks play when they make compare.
It aint no joke, there's a unique bloke,
Beneath this facial hair.

It'd turn me grey what people say,
When I'm strolling around the town,
Why, apart from my belly I could be Ned Kelly,
If my hair was a bit more brown,
W.G. Grace had a barbate face,
Though perhaps not quite as hoary,
And Ho Chi Min's, though a bit more thin,
Was his countenential glory.

So I'm nothing at all like the bloke in the mall,
With the bright red pom-pom hat,
A marketing play from the USA
I'm not, and that is that.
I sing great songs and folk sing along,
I perform to wild applause,
And I'll sing this, chum, ad-nauseum
If you dare say I'm Santa Claus.

So to hell with the henna and the burnt sienna,
And I'm not gonna trim it short,
Go and embarrass that bloke Rolf Harris,
Tie your own kangaroo down sport.
There's more out there than facial hair,
If you need some cause for offence.
Till the day I've died, I'll wear with pride,
This beard on my countenence.

I don't look a bit like Santa Claus,
My verdict is official,
If the beard on me is all you see,
Then your look's too superficial,
There's Karl Marx and Henry Parkes,
With whom I could be compared,
but it's plain to see that you don't see me,
If you just see a big white beard.
