Chicken 65. What is it and how do you make it?

Call me ignorant or what, I did not know about "Chicken 65" until I saw it as one of the buffet items in a local Indian restaurant here in the Metro Detroit Area.

So what is Chicken 65? According to wikipedia

The number 65 is variously said to be the number of days taken to prepare the marinade or the year of the dish's creation. One account claims that the dish emerged as a simple meal solution for Indian soldiers in 1965. Another credits the Hotel Buhari in Chennai with creating the dish. Whether true or not, the hotel remains known for serving Chicken 65 to this day.

Other accounts claim that an "enterprising hotelier" targeted macho diners with a 65-chilli recipe and named the dish accordingly. It is generally acknowledged that no one knows which (if any) of these anecdotal theories are true.

Then there is this video from YouTube which not only shows you how to make "Chicken 65" but also attempts to explain the origins of "Chicken 65".
