Ok, I saw this a while back and it's quite possible it's already been linked to from here or seen by most already... but here goes:
It's a cover of We Weren't Born To Follow by a 27 year old from the UK. I wasn't into the song yet at the time I saw this, but something about his delivery held my attention and I actually started to get more into the song because of this. The clips from various other live appearances tend to be annoying, but other than that I appreciated the fact he put through a convincing performance of the song when it was so new at the time.
