Based on a clip in one of the Instagram stories on the official Challengers instagram page, sounds like we're getting some singing from Trent on the score!
This link should bring you directly to the particular story, if you have an Instagram account. Until the story expires, anyway.
EDIT: Someone ripped it and posted it on Reddit for all to see and hear!
