Brian Day 18 vs Brad

Escaped with a 4(2)-4(2) tie yesterday, very nice.  Ben, we're in a battle for last place in C, it seems.

4/6 today, feeling good since I was only confident of two of them.

1) SpaceX.   The only private one I can name (Virgin Galactic is public), hoped it wasn't the Bezos Blue company. 1/1

2) Quattro.  It was always cool when she was in an episode.  I don't get this without knowing what four cheeses is in Italian, but quattro rang a bell.   I think this is impossible without the Italian hint, but as it stands it's impossible to defend. 1/2

3) Earl grey.  Gimme of the day?  0/0

4) Paperback Writer.   No clue.  3/2

5) Banksy.  No clue. 2/3

6) Spain.  I'm a big William of Orange fan. 2/1
