This is so exciting!
'88 Keys', who's album cover 'The Death of Adam' was revealed in the first clue, is a big fan of Ralph Lauren clothing, who use the Polo Player logo as part of the clothing brand. He enjoys the lifestyle so much, they have a blog called "I Heart My Polo Lifestyle".
I've just subscribed to the blog to catch the clue as soon as possible. Oooh boy!
