You're Not Breathing Well?

I find that if i'm doing an impression, some days it just sounds like john c riley's in the room. Sually didn't prep it like itwas just, it just came up in codelation and i just do it cause i'm comfortable. But then if you go, like, in ten seconds, johncy riley gets a hair cut, ten not like on it starts, it might be off. I can hap the pitches off, cause the stress literally constricts my vocal cords or something. Thing's a little off pitch. Would you talk? You're not breathing as well. That's it? Yes, yes. So you are restricting it
