Beyonce's hit track Irreplaceable has been adopted by teachers at a school in Wales to remind pupils to keep to the left.

The track, which appeared on the star's 2006 album B'Day and features the lyrics "To the left, to the left, everything you own in the box to the left", has been taken up by bosses Bryngwyn School in Llanelli in an attempt to encourage students to maintain an orderly system when making their way around the corridors.

The bizarre tactic appears to work a treat - headteacher Paul Jones says, "The purpose was to improve the smooth and effective transition, as pupils and staff travel around school between busy lesson changeovers. It is quite surprising, not only do the pupils enjoy it, but they responded and it does work."
