"Open Arms" on Dancing with The Stars Tonight

It wasn't a Steve Perry version, or any Journey singer's version. There were four singers
in the credits, two men and two women, so I assume one of those singers sang the song.
It was pleasant to see the dancers dancing to the song, but whoever sang it didn't really hit
the notes. I wondered why they didn't just go with the SP version. Do you think the use rights
would have been too expensive?
This is the best version ever........... I love this song and how SP sings it here.
