I don't think anyone could write about another culture and get it 100 percent accurate.
I also remember the second band I was in ever. We were called Hybrid. We got a show at this local street fair, and we were playing on the back of a flatbed truck. There was an ad in the paper, and it said that 'Hybird' is playing. I was so mad.
I'm not against accents - my husband's from Lancashire and has a rural Lancs accent. We've just got back from Scotland yesterday, and I love that Highland burr.
