"Time for Heroes" is a song by English rock band the Libertines, featured on their debut album Up the Bracket.
Writing under the name Heavyhorse to fans on the Libertines web forum about the song, Doherty explained the meaning behind the lyric "wombles bleed, truncheons and shields": "The 'wombles' were a revolutionary sect from the era of the Mayday riots in the year 2000.
They were rioters who all dressed up like wombles from the t.v series, including tinfoil shields and wobbly truncheons, mimicking the riot police.
It is also widely acclaimed, coming in at number 2 (behind "Last Nite" by the Strokes) on NME's list of the best 50 songs of the previous decade.
A music video for "Time for Heroes" was filmed in Madrid, featuring the city's Metro and Colon's Square.
