If it wasn’t obvious I love this composition

So you want to write a fugue? You've got the urge to write a fugue You've got the nerve to write a fugue So go ahead and write a fugue that we can sing Pay no heed to what we've told you Give no mind to what we've told you Just forget all that we've told you And the theory that you've read For the only way to write one Is just to plunge right in and write one So just forget the rules and write one Have a try, yes, try to write a fugue So just ignore the rules and try And the fun of it will get you And the joy of it will fetch you It's a pleasure that is bound to satisfy So why not have a try? You'll decide that John Sebastian Must have been a very personable guy But never be clever for the sake of being clever For a canon in inversion is a dangerous diversion And a bit of augmentation is a serious temptation While a stretto diminution is an obvious solution Never be clever for the sake of being clever For the sake of showing off It's rather awesome, isn't it? And when you've finished writing it I think you'll find a great joy in it (hope so) Well, nothing ventured, nothing gained, they say But still it is rather hard to start Well, let us try Right now? (yes, no) We're going to write a fugue We're going to write a good one We're going to write a fugue right now!
