The HD Version of the Extended/Full Theme Song was just released.
Now we can watch and listen clearly to it.
But during the line...
"The odds are against us, this won't be easy, but we're not going to do it alone!"
Some/Most people claimed that Peridot sang along in this part, while some claimed it was just Steven.
To clear things up, I created this voting thread to know whether Peridot sang along in that part or she didn't.
Before voting, make sure that you listened to that part carefully.
To vote, write Support if you hear/claim that Peridot sang in that part or Oppose if you claim that she didn't.
