A letter from Wales

We have got some friends in Wales and they sent us a letter to say thank you for some cards we sent them.  In the letter they told us about the longest train station name in the world.  It's the name of a station in Wales and the word is Welsh.  Here it is:

Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch

Our friends said that not many people know how to say it and we saw this as a challenge.  We are going to use the video below to practice saying it and see if we can learn to say it.  Can you say it?
