McFly are amazing. They write and compose their own songs, and that's very rare nowadays. And it's not very hard to understand that they're like brothers. That is true friendship.
together they are simply heaven on guitars, the fact that the are still together and that they can still revisit it and that it's relevant is something to be amazed by. They are what every band should aspire to be, together not just for people but because they truly love each other.
