Hey people! This is the first tab I've submitted so try not to be too harsh ;) this is such a great song and it's really fun to play. It's only the first single that they've released off the new album 'Liberation Transmisson', but if there are more songs on the record like this one, it'll be another brilliant one from Lostprophets.

The Interlude follows the same chord pattern as the Chorus, again, it has another strumming pattern again.
Guitar 1 & 2 - Distortion   "Standing on the rooftops, waiting 'til the bomb drops!..."

The same applies for the second Breakdown part of the Interlude; the chords are the same, different strumming pattern!
Guitars 1 & 2 - Distortion    "Scream your heart out!..."

That's it, the ending of the last chorus is a little different, you have to hold the last two chords; but this will sound easy once you listen to the song. Enjoy playing; just listen out for the strumming pattern changes in the last bars of the song!
