Just bought a CD copy of 3b at a second hand shop in Spain. The booklet is seemingly signed by someone, unrelated to band members. Inside some of the songs are circled and have a bunch of annotations I can't really decipher, they don't seem to be in Spanish either. Could this be from an amateur musician? Are these songs related to the annotations in anyway? Is it just a crazy person? It'd be nice to have someone else's perspective here. Also, "San Francisco" is highlighted at the end page for some reason.
