1. Twist and Shout
3. Titanic survivor
4. someone who played tennis
5. Having looked up the middle name, I don't understand the clue.
6. Something like "pulling out all the stops." This should trigger a Cryptonomicon quote, but I'll let it slide.
7. First thought was something along the lines of borders on different major bodies of water. But I'm not sure all would qualify and I can think of a few more that would. Second thought, maybe noncontiguous borders; but then New Zealand would have to be on the list. East Timor seems like the wild card and I'm drawing a blank.
