Which ad is this from?

Boy Division

I apologise if this is the wrong place, but I couldn't see anywhere else that would be appropriate as it's not really the song I'm looking for but what ad it's from. The television board seemed the most correct location. A friend of mine hummed this to me the other night and we haven't been able to figure it out. This is me whistling it as best I can:

If there is somewhere else I should have posted this instead then the mods can feel free to move it.

Thanks for any help.

The version in the Baileys Ad is by a band called 4-Hero and called Le Fluer.
I think that there are a few different reworkings of the original over the years.
