King George's speaking

In the three songs that King George appears in: I know him, What come Next, and You'll be back one of the few things in the lyrics that connects the songs is, "They say, and
Da da da dat da dat da da da da ya da
Da da da dat dat da ya daaaaa!
Hahahahahahahahaha" The first part is a little unusual since even though he is singing he is using other peoples opinions to start his song and since he is a king you wouldn't expect him to use others opinions. It's also interesting that in You'll be back he uses You say unlike the other two, part of the reason is due to the colonies not being part of Britain anymore. Now as for the part that is him saying random words this part is used to portray his emotions in each song. In You'll be back he is very happy when he is singing signifying that he is confident in his victory, so why should he worry about losing the colonies. In what comes next this is reversed as he now has lost the colonies, the song also shows how he feels betrayed that they have left him for France. It is also used to foreshadow the coming events for America as we later see in the musical. Then in the final one I know him he is still sad at the beginning which shows he is still sad while also showing his confusion with the concept of stepping down and giving up your power. Then in the second half of the song he is back to his happy self as he realizes that this will cause trouble for America as he knows that Adams doesn't have as much backbone as Washington does. For me these choices show how much America meant to King George the III, it also gives us an outside reaction to key events that take place. What do you think? Why do you think Miranda had the lyrics be so similar, is it similar to how he does it for Hamilton and Burr or is it different?
