There would appear to now be Asian influences coming to the fore as a spin off from Bollywood. Back in the 70's I knew an Anglo-Indian guy who sang English traditional, albeit with an Asian twist. For instance he sang Young Sailor Cut Down in his Prime as Young Sepoy Cut Down in his Prime. IMO being a much smaller country than the US we have had to integrate more and absorb other cultures including their musical styles without actually realising it at the time.
