Kim about I Can't Say Goodbye
I remember going in [at RAK studios], I remember seeing the orchestra in there and being in the control area. It was overwhelming. It was so overwhelming. I was so proud. It was one of those moments I have as a postcard in my head. I was seeing the strings happening on this song that had happened on a piano in my flat. So, yeah, it was one of the magic moments. (1)
