Save The Children or Unicef

Ok, I actually can't remember the number of year, but it's a few years back. It's either an STC or Unicef ad, can't remember specifically. The music consists simply by an acoustic guitar playing through the whole 30'ish long commercial. Very simple tune, though very emotional. Have been looking all over the internet for it, soon to give up. It's driving me
mad. ANY help would be much appreciated!
