A question about the song "Melting Pot"

Could I ask a question about the lyrics to "Melting Pot" from boyzone?

Could somebody tell me who Mick and Lady Faithful is?
Thanks so much.

Here are the lyrics:

Melting Pot Lyrics

Take a pinch of one man
Wrap him up in black skin
Add a touch of blue blood
And a little bitty bit of
Red Indian boy
Curly black and kinky
Oriental sexy
If you lump it all together
Well you've got a recipe
for a get along scene...
Oh what a beautiful dream
If it could only come true
You know, you know...

CHORUS:
What we need is a great big melting pot
Big enough to take the world
And all it's got
Keep it stiring for a hundred years or more
Turn out coffee colored people
By the score

Brothers and the friars
Bishops and the gurus
We had the Beatles and the Sun Gods
A long time ago (it's true)
But then it didn't really matter
What religion you choose
No no no...

Mick and Lady Faithful
And everyone who's graceful
You know the living could be tasteful
Why don't we all get together
In a loving machine
I'd better call up the Queen
It's only fair that she knows
you know you know...

CHORUS to fade
