Never mind the leaders' debates last week, this could be the moment that The Green Party really make their mark upon the mainstream voting public.
Knocking the Lib Dems' bizarre Uptown Funk cover into a cocked hat, they have released one of the most unexpectedly brilliant party political broadcasts ever created.
Painting the leaders of the other parties as so 'in harmony' that they could be in a boyband, it sees 'Clegg', 'Cameron', 'Miliband' and 'Farage' teaming up to sing a ridiculous ballad, complete with gang vocals and synchronised dance moves.
And yes, of course, there's a key change, led by Clegg. Given Cameron's record on U-turns, it's surprising it wasn't him.
Really, mere description cannot do this piece of genius justice. Watch below and see what you think.
