I've had the studio version since a week after idol gives back.
i listen to it every day until now.
And dc's voice there is so pretty obvious.... and all wordnerds should be able to tell. haha
but anyway, his parts are:
At the sound of your name (in the chorus)
and he shouts a lot at the end along with Carly.
at the sound of your name is definitely not jason.
jason didn't have a solo part in the song.
he was only back up for kristy in the beginning.
DC, Archie and Carly owned the song
