But where do you draw the line then? Would you not feel a little uncomfortable if you heard, for instance, a white English person affecting a Trinidadian accent to sing a calypso song? I've heard precisely that on an otherwise really enjoyable British folk album. I wasn't the first or the only person in the room to cringe. Now obviously there's a lot more recent historical and cultural baggage attached to that particular example, but for me it's the same root unease.
