Baby, I'm mad The craziest friend that you've ever had
You think I'm psycho, you think I'm gone
Tell the psychiatrist something is wrong
Over the bend, entirely bonkers
You like me best when I'm off my rocker
Tell you a secret, I'm not alarmed
So what if I'm crazy? The best people are
All the best people are crazy, all the best people are

The three steps before modern english were indo-european, germanic, and old english. as peoples moved around the eurasian continent, their languages changed. throughout the ages, the languages became more specialized. as english has many germanic influences, it is easy to see how this was one of the forebears. also, old english was one of the main ancestors of the modern language, spoken in the 5th through about the 13th centuries.
