Jake - scary that you should mention this.
I play piano by ear but yesterday at my folk's place for Easter, my dad (who can play guitar well) was trying to figure out NGBA. I got inspired and had a go, and soon found myself playing something remotely similar to The Chain. When I got home today I recorded it! Not bad for second day on guitar, but be prepared for a giggle, especially when I make the mistake of trying to sing on it, despite having to sing so softly in order for neighbouring apartments not to hear. (I started singing and I thought I heard the people upstairs packing their things.)
