Already asked [[http://typophile.com/node/34307|here]], [[http://www.typophile.com/node/106798|here]] and re-asked [[http://www.typophile.com/node/106900|here]] and still unsolved. So I'm afraid and even if your request is URGENT that might probably be a custom lettering for the brand. I suggested [[http://www.myfonts.com/fonts/laura-worthington/yana|Yana]] as alternative but far from being even loosely similar.
Funny also because the more I look at it the more /P looks completely off-topic, some kind of [[http://www.myfonts.com/fonts/hihretrofonts/figgins-tuscan|Figgins Tuscan]].
Closer look and more letters [[http://myfonts-wtf.s3.amazonaws.com/1b/1b9e5bb6d759a60b10456e812065ef29....|here]].

Agree wholeheartedly with Ryuk—this is a custom wordmark.

As a base for recreating all but the cap initials, try Austin, by Commercial Type (will require editing):

For the initial caps (and that |O|), these faces from Letterhead Fonts may be a decent starting point for editing:

And this one:

Austin is an interesting suggestion, with a good match for the serifs.
Note that the "Austin Text" version seems to have a contrast that more closely matches the wordmark than Austin does. Also, Austin Text Roman seems a closer weight than Austin Text Semibold.

Alternately, Austin Roman can be used to produce the correct contrast if parallel stroke is applied
