How to get from Gare du Nord to Gare de Lyon in Paris - 55 Min connection time.

Hi all.
Here is a quick informative video of how to get quickly from Gare du Nord to Gare de Lyon in Paris.
Useful for travellers coming from the north heading to the south of France.
In this video, I am coming from London into Gare du Nord and heading towards Spain on a train departing from Gare de Lyon.
I only had 55 minutes to make this connection. Can I make it? Watch and find out.
Thanks.
