Consider Green Day, a band made up of Californians who sing in a working class British accent. The British bands of the 60s sounded semi-American when singing because they were trying to, and the British Invasion bands were trying to sound more American because it was where the market was. The British punk and Britpop bands didn't try to sound American or even mid-Atlantic.
