I think it would be really rude not to seeing as she recorded here, used an English choir and has a song called London.
True. A 'London' show ought to be planned. I'm actually surprised she didn't have any small gigs while she was there recording. It would've created some buzz for the album, especially seeing as how it contains so many English elements.
Yeah, she doesn't need to really promote, just stick it on twitter/facebook and it'll sell out easily. Also, I think she'd do well from promoting the album here. I think her style of music would do much better over here. I mean, our biggest star is Adele and America has Lady Gaga (who I love). I just think Brits are less into pop and are more into her kind of music. Plus it's really easy to reach loads of people. When BNN was out I don't remember seeing lots of TV interviews but she had a TV advert and was on the radio a lot. We don't have many big stations or channels, so it reaches many people without having to spread promo around.
