I heard this song at an airport...

[hughes18]

It's a ballad/love song kinda thing, sang by a man, and the start of the chorus goes...

"It's not where you go when you die, it's how you live while you're alive."

...and that is all i can remember. Any help with song name or artist would be fantastic, thanks.

[Juliëtte]

I think you mean this song:
Dr Frankenstein by Jack Savoretti

It is indeed, thanks for your help!
