IT is one of the most spectacular sights in Scottish culture – the full panoply of the troops at the Edinburgh Tattoo, marching in step to stirring music and cinematic light.

Now the Royal Edinburgh Military Tattoo has the globe in its sights.

Under ambitious new expansion plans, the event is to be staged in a series of spectacular shows in Australia in 2019, China in 2020 and Canada in 2021, with more countries to be announced at a later date.

Brigadier David Allfrey, the chief executive and producer of the Tattoo, said he wanted to double the turnover of the event to £20 million by 2025.

He is also hoping to see its audience increase tenfold, to one billion people.

The Tattoo has been abroad before – staging shows in Australia and New Zealand in the last 15 years.

Now the organisation is considering several venues and variations of performance ideas for the shows in Australia, China and Canada.

Mr Allfrey said that the move was a “step change” for the festival, which remains popular but is bound by the physical size of its annual venue, the esplanade at Edinburgh Castle, which has room for 8,800 seats per show.

The new strategy will be a challenge for the team of 22 people who run the annual festival as they will be producing six shows a year. The usual working method is to plan the Tattoo of that year, plus the two following years.

The producer said that the board of the Tattoo had decided that this was the right time for the expansion, adding it would bring “huge collateral benefits” to the festival and the city.

The Tattoo sells 220,000 tickets for its Edinburgh show each August, generating £77m annually for the UK economy.

The 2016 performances in Australia and New Zealand generated more than 240,000 tickets sales, generating an economic boost worth £50m in the cities of Melbourne and Wellington.

Mr Allfrey declined to reveal which cities would receive the show, but said that the benefits of working with highly experienced large demonstration show experts in China were clear.

“The Tattoo is one of the greatest shows on earth, attracting audiences across the globe to Edinburgh and selling out year on year,” he said.

“We are a small company but we have big ambitions and are focused on delivering a show that is bigger and better, more technically advanced and visually thrilling every year.

“Edinburgh is an amazing stage and will always be our home, but for us to continue to thrive as an organisation, we need to look beyond the esplanade and the walls of the city.”

He said the “Tattoo is like any other company, it has to grow and it has to get better”.

The Herald:

Work is already under way to expand the annual event’s international reach.

Most recently, the Tattoo’s own house band, The Pipers Trail, has been sent to support cultural exchanges in Germany, the Czech Republic, Norway and China.

Mr Allfrey said that the latest expansion plans had been considered carefully and were being implemented in an “extremely prudent” way.

“This announcement sets out our ambition to continue [our] success, building a strategy for growth that will take us to new territories with new partners, but always with the intent to deliver not just great entertainment but employment, investment and commercial returns as well,” he said.

“Our aim is to continue to grow revenue streams overseas, so we can continue to successfully deliver commercial benefits and reinvest in Scotland, something we already do to the tune of £77m a year and we have the ambition to do so much more.”

Mr Alfrey said that previous oversees shows highlighted how “there is a huge appetite for The Royal Edinburgh Military Tattoo internationally”.

He added: “The Tattoo is proud to carry banners for Scotland, Great Britain and a host of international partners to benefit relations between nations, promote trade and investment, encourage tourism – inbound and outbound – and to showcase diverse cultures and heritage.

“We are in the unique position to be able to bring together military and civil societies, link Scotland with the international community and strengthen ties with current and future British allies.

“So we are excited to reveal these plans and invite our key partners, sponsors, supporters and audiences to join us on this journey to new destinations and long-term success.”
