I got a reply from that guy who posted a video of the POM video shoot on YouTube but he took it down:
Well I took it off because I was in her music video for the second part of shooting, it was all day and I got to meet her and she was really nice and down to earth which surprised me because I had heard she was mean. She works really hard and I didn't want to be an ass and put something on YouTube that shouldn't be there.
"'I Will Be' is a song I have known for a while… From the outside looking in I know that everyone was fighting for Avril to put this on her record but for reasons I will not disclose, Avril, did not... I remember Luke playing this song for me months ago and I was at the point of tears knowing I heard a song that would be the hugest thing ever… I mean, people, be prepared to hear this song at EVERY WEDDING for a LONG time."
