With just 28 days to go until the general election, the parties are beginning to pull out all the stops when it comes to humiliating their rivals.

So it came as no surprise when The Green Party unveiled their new campaign video, which features actors playing David Cameron, Ed Miliband, Nick Clegg and Nigel Farage singing in harmony with each other.

[related]The parody track 'Change The Tune' sees 'David Cameron' sitting at a piano (watch out Elton) as he tells viewers a 'vote for me is the same as a vote for any of us guys'.

During a particularly moving verse, the group ask 'Eddy' to 'join the band' before they show off their attempt at... dancing?!

If you're over 18 and register by April 20, you can vote in the general election on Thursday 7 May, 2015.
