If you've already watched 'It's a Sin', you'll be well aware of its fairly banging '80s pop-themed soundtrack.
You'll also known that the show's main character, Ritchie, is played by Olly Alexander - who just happens to be the frontman of synthpop band Years & Years as well as a very fine actor.
It was inevitable that Alexander would bring both of those elements together at some point, and indeed, he recently performed a stripped-back cover of the show's namesake - 'It's a Sin' by Pet Shop Boys.
He said: "“I’ve always loved the iconic Pet Shop Boys and this song’s expression of the gay experience. My character Ritchie loves this song too so I’m really excited to put out our own version. I made this mostly from home just me and my piano so it feels pretty raw and exposed, it’s a really beautiful song to sing.”
Now they have shared the accompanying video which features clips from the show that might make you bawl all over again (but don't worry if you haven't seen it yet - there are no spoilers, either.)
