TVZap has posted an article on Keanu’sappearance on C’è Posta per Te. It also gives the details of why he was asked to the show and there are nine photos. It is in Italian. It translates well and delivers the message slightly differently.
Update: TVBlog appears to have live-blogged the show while it was on. Keanu was on first so you will have to keep hitting the gray bar at the bottom to get to the beginning of the show. They have a photo and a description of what was happening. Thanks to Ayako for tweeting the link!
Update X2: Here is another article with 4 photos.
