Thanks Rob and Torrey ,
Yeah the concept was hard in the sense that a song about the Titanic could become very corny very quickly and I took the decision not to mention Titanic except in the Title.
Her vocal is perfect for the song and she was amazingly professional.
On the video production the credits including an animated logo were done on microsoft power point which can make a presentation into a video (2010 onwards)
I was surprized how much I got out of powerpoint to be honest.
Thanks for the comments really nice Hugh
