The legal sector is the latest to catch the choral bug (cue jokes about solicitors singing for their supper).

Global firm Norton Rose last month sang its way to the Office Choir of the Year 2012 award after a virtuoso performance in London. Singing pieces from Handel and Beethoven - as well as the slightly more modern Somewhere Over the Rainbow - Norton Rose held off competition from fellow law firm Olswang as well as UBS and Channel 4.

The 50-odd members fit practice in around a busy work schedule, with rehearsals held before office hours on Thursday morning.

The choir’s next public outing is the City of London Festival in the Guildhall Yard on 3 July.
