Unprecedented scenes of rock ‘n’ roll anarchy dominated last night’s Law Rocks, as for the first time two bands tied for first place.

Addleshaw Goddard’s AG/DC and Clover from Southampton’s Coffin Mew both took the top spot as the first-ever joint winners of the legal market battle of the bands charity fundraiser.

The partisan audience initially threatened to riot after the result was announced but then changed its mind after a wave of politeness and mutual congratulations engulfed the legal market crowd.

The judging panel had found it impossible to split the two bands and called for a sing-off. Coffin Mew went first, booming out Queen’s Fat Bottomed Girls around London’s iconic 100 Club with the entire audience singing along.

Addleshaws responded with an epic version of Florence & the Machine’s You’ve Got the Love.

As both songs ended the audience went wild and amid the madness, host Damian Hickman, the managing director of the International Dispute Resolution Centre, averted an almost certain catastrophe by announcing a dead heat.

“Oh my God!” commented Law Rocks founder and Navigant managing director Nick Child. “There was never a closer call than that.”

Rock god Anthony ‘Ant’ Carroll of Keating Chambers, who was one of the judging panel last night, commented: “Another brilliant Law Rocks. Well done everyone. I think if we’d had to pick a winner, we would have had beers thrown at us from half of the room, so it’s a good result.”

Fellow judge and South African lawyer Johan Beyers said: “Awesome night out, the bands were fantastic”. He added: “We must do this in Cape Town.”

A version of Law Rocks in South Africa is far from an impossibility. Since launching six years ago Law Rocks has become a global phenomenon with events in Los Angeles, Dubai, Tokyo and most recently Vienna at the International Bar Association.

Over the past six years it has raised hundreds of thousands of pounds for a variety of charities, and allowed hundreds of lawyers and legal market staffers to let loose their inner rock god.

Last night those lawyers included a batch from Gordon Dadds, fresh from snapping up half the UK legal market after deals with Davenport Lyons and Jeffrey Green Russell, which fielded its band Daddness.

The band’s set included not only probably the most entertaining lead singer of the night but also a rare sighting of a trumpet at Law Rocks.

TLT kicked off the night with The Who’s Won’t Get Fooled Again. Sadly while the band, TiLT, did its best to channel Townshend, Daltry, Entwhistle and Moon it utterly failed to kick over the drumkit, windmill or have any on-stage punch-up whatsoever.

The Hughe Fighters, a group from commercial property consultancy Hughes Ellard that had won this year’s Solent Rocks and a spot in last night’s competition, completed last night’s line up.
