Relativity, play on Radio 4 today what was was the song at the end?

[Grammar]

Just listened to the play, really lovely closing song.
How do I find out who wrote/ composed and sung it?
Did anyone else hear this?

It's called 'The Luckiest' by Ben Folds Five. It was used in the film 'About TIme' as well.

Thank you both. I have seen ' About Time' and liked it but didnt pick up on that song, quite beautiful, thank you.
