It's a song by The Parks, and you can listen to it on their MySpace. The Parks are one of my favourite Irish bands. It's such a brilliant tune. The Parks are a band who have been around for quite some time (despite their youth) and one that I personally think could do big things. I just really like their vibe. It's rough as hell, but great. Great singer too.
Here's a song called 'Young Professional' they did at Muzu.
