I have heretofore avoided expressing my views in any of these 'accents' discussions (I think), for the reasons I gave in my initial post to this thread. However ... as a singer, I take inspiration from the Canadian field recordings made by Helen Creighton, Edith Fowke, et al, in which, although there are vast numbers of songs of Old Country and (less often) American origin and/or setting, you never hear a singer use anything other than his/her native accent. The result is the effect that the singers really 'own' their songs, in the sense that they have 'made them their own'. Listen to any of the appropriate samples from the Helen Creighton collection to get what I'm talking about.
