Hi TEEEJ and Airborne Aircrew. Sorry but I caused the confusion. I saw what Airborne Aircrew saw this morning and changed the links so they worked, but I was in a heck of a rush as I was off to see aged pa-in-law in Sussex, so didn't "leave a note".
For your interest, all you have to do for youtube clips now is copy the URL from youtube and then paste it directly into where you want it in your post. Automatically embedded.
Sorry again.
