Help me find a song please! Desperate!

So I was being driven by my friend a couple months back and on his radio a song starts playing, rather mellow affair. I liked it a lot and just now it was playing on the telly again for a few moments, much to my frustration. I should invest in that app that names songs for you...

It's a duet, a man and woman singing in turn, sounds very romantic There's a piano occasionally and then they both go "Oh, Oh Oh Oh" for want of a better description. Couldn't be anymore vague I know, all I remember is at one point the bloke mentions "something rattling the cages" or very similar. I'm pretty sure it's a modern song, past year or so.

Does anybody have any ideas? Cheers

To help with our investigations, can you remember what was on the television when the song was playing?

Can't find a duet version though sadly, nice song though.
