I look at older issues an didn't see anything about the specials. The content bible says that "Some DVD bonus content is allowed" and was wondering if the following could be added.

"Tank!” Full-Size Music Clip (basically an extended intro)

“Tank!” Club Remix Music Clip -UK Version (similar but different than the above)
