In my top five Bloc Party favourite tracks of all time without a doubt - released as a single in October 2005 about 8 months after the debut album Silent Alarm.
Incredibly catchy chorus, sad yet uplifting lyrics in typical Bloc Party style, combined with superb drumming as ever from Matt Tong. I have listened to this on repeat play for sessions at a time - still not wearing off - classic.
Well worth paying for seperately in my opinion but also available on the UK re-release of Silent Alarm in October 2005 - which includes a DVD and 2 bonus tracks, this and 'Little Thoughts' - and therefore that is probably better value overall.
Either way make sure it's in your collection...
