This song is about a man that my mate, Crazy Horse, and I chose randomly from the Dublin phone book, called Brian Oliver. We sent him post cards while we travelled the world. We pretended he was our mate and had been for years. We did this for three years. But we never gave our full names or a return address. I did eventually meet the guy which was quite an experience, but that's another story.
This song is a tongue-in-cheek dig at Brian for never writing back, but of course he couldn't because he didn't know who we were and we never gave our address.
