British Lion bass

Out of curiosity, has anyone learned how to play any British Lion songs on bass?

At this point I've (more or less) figured out "This Is My God", "A World Without Heaven", "The Chosen Ones" and "Spitfire". For the most part, they're not very complex (generally on par with Maiden songs from the past few albums). For the most part, they use lots of Harris's standard techniques (lots of power chords, root/fifth patterns, etc). No galloping in any of these songs, and not a ton of fills.

Has anyone else had any interest/success in learning these?
