I think that Friend would make a great single that could possibly do well but I would interested as to when/if singles will be released in the rest of the world. In Australia I think it is released next week but there has been no publicity. I would be interested to know because the US/Canada is basically the last place in the world to have it released.
If anyone still hasn't ordered or received their copy I found a great site I got mine from and it works out pretty cheap (sorry if this seems like advertising or is repeating a previous post). It is US$16.99 with free delivery from the US site and GBP8.99 from the UK site.
