There was a lot of Norse cultural influence in the North of England, but of course they had a lot of linguistic crossover with the Anglo-Saxons. In some recent historical TV shows the cultural differences between Anglo-Saxons and the Danes are exaggerated for narrative reasons, but they could actually understand each other's languages reasonably well. The influence of Anglo-Saxon culture is the main reason why English culture isn't the same as French culture, so I don't think you can really say it's defunct. The influence of French is stronger in southern 'BBC' English, but England has a lot of regional dialects that still retain a lot of quite ancient linguistic influences.
