Since it's the 30th anniversary next year I'd be pretty surprised if they didn't make some sort of change to the theme. Then again, they've had the same end cards for about 7 years and essentially the same theme song arrangement for 10 years.
I wish we'd have proper credits again. I never understood the timing concerns, hasn't the show been running on the same 20-25 minute timeslot for the past 29 years? They managed the long titles fine in the beginning.
Call me weird but I actually liked his version. Both the singing and the arrangement, when they changed it they sort of watered down the instrumentals a bit.
