David Maddox: Was the Labour Party trying to tell Gordon Brown something?

M People's Moving on Up sounds pretty uplifting when you're a party staring defeat in the face, but on closer inspection it is an odd choice of song to play Gordon Brown off the stage with, perhaps in more ways then one.
Read for yourself:

You've done me wrong, your time is up
You took a sip (just a sip) from the devils cup.
You broke my heart, there's no way back.
Move right outta here baby.
Go and pack your bags.
Just who do you think you are?
Stop acting like some kind of star.
Just who do you think you are?
Take it like a man baby if that's what you are.

[chorus]
'Cos I'm moving on up.
You're moving on out.
Movin' on up.
Nothing can stop me.
Moving on up.
You're moving on out.
Time to break free.
Nothing can stop me,
Yeah.

They brag a man has walked in space,
but you can't even find my place.
Mmm there ain't nothing (not a thing) you can do
'cos I've had enough of me baby being part of you.

Just who do you think you are?
This time you've gone too far.
Just who do you think you are?
Take it like a man baby if that's what you are.

[chorus]
