Hi Everyone!
What a mouthful! 😮
Now have you ever been at a concert and all of a sudden there’s confetti, paper horns blasting, people yelling more, more, more!!!!
That’s “brouhaha“
Then the leader waved his guitar in the air,
Everyone quieted down,
One note was played and the band walked off the stage. 
The crowd was in shock 😮 😮. And I do mean shock!
And then the “hubbub” started!
Megaphones being used
, people screaming 
, raising home-made signs, etc, etc, etc.
Have a great day! Hope
