Composer could be "Paul van Brügge" as stated here:

Theme doesn't seem to have been changed over the recent years, as I've checked several opening's by using YouTube.
Though I have to admit, I also expected a band's name.
I will keep my eyes open, if they use a theme that long there has to be additional information on who did this.
