Just off to try it now. I doubt I'll find my great-grandparents though. Either they were indexed wrongly in the central GRO records (happened in a very large number of cases), or didn't actually marry! Oh or married in Ireland (bride from Dublin), but I'm doubtful about that, given the bride probably emigrated pre-wedding.

But this will be very useful for my Cavers one-name study. Off to reactivate my Find My Past account. Thanks.
