If you happened to be watching BBC One's Festival of Remembrance on Saturday night, you may have caught one particular performance that has caused quite a stir.

Leona Lewis took to the Royal Albert Hall stage for the event, which celebrated the 75th anniversary of D-Day and the Battle of Monte Cassino from WW2.

She sang the Simon & Garfunkel classic 'Bridge Over Troubled Water' - an old reliable in such circumstances, you may think - but not everyone was impressed.

Some viewers complained that the former X Factor winner was out of tune, while others lambasted her for her OTT performance of what is generally an understated song.

Her rendition of the tune - which she first performed on The X Factor over a decade ago - proved seriously divisive as loyal fans insisted that she had done a good job.
