Duo wow with stunning performance of Elton John's 'Your Song' on The Voice

Getting a standing ovation from all four judges on The Voice is a very rare feat, but Rachel Mac and Bradley Sinclair did just that during their battle round this week.

Over 50 years after Elton John released his chart-topping power ballad 'Your Song,' Mac and Sinclair belted out a stunning rendition of the 1970 hit and their vocals are something else.

Coaches Kelsea Ballerini, Nick Jonas, John Legend and Blake Shelton were all moved to their feet by the talented singers, with Shelton was shouting "Finally! Finally! A standing ovation!" at the end.

"Honestly, I don't know how you decide with what we just saw there because they were both perfect," said Legend after the impressive vocal display.

Jonas told the singers: "You both just gave the best performance we've had in the Battle Round.

"Unfortunately, I have to make a really tough call here. But I just want to say you're both amazing. You both deserve to be in this competition."

Talk about chills.
