Deletion of Will Page

Comment: Searching for "Will Page" and PRS together helps. I added some sources that I could find that way and removed the unsourced and promotional material. But he seems to be very widely cited in the media as an expert in music finance, and there have been several major news stories specifically about studies that he did, so I think he passes  and #C7 (his academic work has had a big impact outside academia). Some of the text I removed seems to be a copyvio of http://www.prsformusic.com/SiteCollectionDocuments/KEY%20STAFF%20BIOGS/Will%20Page.pdf this piece at PRS but I think it's all gone
