The whole album is bloody great, a real enjoyable listen.
I love all three new tracks although Struck By Lightning really was a "holy shit!" moment on first listen. I certainly wasn't expecting that!

The surprise track for me is "Spanish Sea". This apparently was originally recorded for "Isolation" but obviously didn't make it, and certainly doesn't sound like it ever would have fitted with the rest of the album. On first listen though, I thought I was listening to a different version of "Africa" when it started.
The intro is almost identical, even lasting the same length of time and the underlying rhythm and tempo are pretty well the same throughout both tracks.
