Lulu came joint first in the 1969 contest with Boom Bang-A-Bang

Entrants are much more likely to Boom Bang-A-Bang or Diggi-Loo Diggi-Ley than bash out a Billy Bragg-style paean to the working classes.

But this year has seen a flurry of songs with supposed political content.

Israel, for example, attracted controversy for lyrics which appear to refer to Iran's nuclear programme.

And the Ukrainian entrant was accused of slipping in a reference to the 2005 Orange Revolution by using the phrase: "Russia goodbye".

It later transpired the artist, a drag queen called Verka Serdyuchka, was singing "condensed milk" in Mongolian.

So what are the lyrical highlights of this year's contest? Here are a few of the more memorable moments.

Artist: Roger Cicero
Title: Frauen Regier'n Die Welt

When I found out she wanted to save the environment
I sewed "No thanks" on my parka.

Artist: Serebro
Title: Song #1

Oh, don't call me funny bunny
I'll blow your money, money
I'll get you to my bad ass spinning for you.

Gotta tease you nasty guy
So take it don't be shy
Put your cherry on my cake
And taste my cherry pie.

Artists: Elitsa Todorova & Stoyan Yankoulov
Title: Water

There's a young lad coming from the village
(Mitra-lassiee, Mitra-lass)
Walking by his side is a wild young pony
(Mitra-lassiee, Mitra-lass)
See him walking there!
Hear him singing Eeeeee!

Artist: Kabat
Title: Little Lady

Her den is there by the railway
She collects coins from fountains
And puts them on the tracks
She's building a temple, a tin bridge
The first guest is coming over
So at least his legs won't hurt

Artist: Teapacks
Title: Push The Button

The world is full of terror
If someone makes an error
He's gonna blow us up to biddy biddy kingdom come

And I don't want to die
I want to see the flowers bloom
Don't wanna go capoot ka boom.

Artist: Eirikur Hauksson

Passion killed by acid rain.
A rollercoaster in my brain.
But, how would you know!
