Interviewer:D-6623Foreword: D-class introduced to ask questions regarding 5901's origins.
<Begin Log>
D-6623: So, uh. I guess the first question on the list is where you are from.
5901: Oh that's a simple question. I was born up in a little town in England. Used to be a comedian at the local bar, had a side-job as a composer.
D-6623: Ok next question. How did you get like… This?
5901: Oh well it's actually a funny story. I was killed my sleep and stuffed in my own piano. Funny, isn't it?!
