Friday marked the highest-profile event so far for the eight-year-old Peace One Day campaign - a movement devoted to the worldwide adoption of an annual day of global ceasefire and non-violence.

As is always the case when celebrities and good causes come together, there were a few occasions on which the worthy gave way to the downright cringe-worthy, but Annie Lennox's appearance at the top of the bill brought the night to an electrifying conclusion.

A speech about humanitarian issues by an infuriatingly handsome Jude Law was followed by the bearded, benevolent presence of Yusuf, formerly Cat Stevens. An updated version of Peace Train and a cover of Saturn by Stevie Wonder were pleasant enough, although a couple of old favourites would have been appreciated.

After a rather embarrassing sponsored appearance by Linford Christie, James Morrison took the stage to inject some real soul into Wonderful World.

Annie Lennox was a worthy headliner, bringing the crowd to their feet with her breathtaking voice as she opened with a sensitive rendition of Little Bird. Walking on Broken Glass gave the 52-year-old a chance to show off her uniquely animated stagecraft.

The crowd was made ecstatic by Sweet Dreams and her 1992 hit, Why, provided a heartfelt encore.
