Behind the scenes – how the stunning light show at CUBG during the Coronation Concert was created

Take a peek into the the work that went on to bring you this beautiful display

09 May 2023

We hope that you enjoyed the show last Sunday night when our Black Pine (Pinus nigra) tree was lit up for the Coronation Concert by pedal power!

The tree looked spectacular on the night and the sight of it, plus the team of cyclists powering it, was beamed across the world and seen by millions – but what did it take to get that fantastic effect that everyone enjoyed on the night?

As you may expect, an awful lot of planning and organization went on to put on such a big event. Nearly every team from the Botanic Garden was involved – from Horticulture to Communications, Visitor Services and Curatorial. The planning started weeks in advance (though on a need-to-know basis as the project at the BBC’s request had to be kept secret until the reveal on the night itself), with the BBC and lighting team coming in to find the best location in the Garden and plan logistics.

The cyclists also needed to be recruited – which was a team effort from a number of Cambridge University institutions that have a link to areas of the King’s interest – particularly green energy and conservation.

While it was all alright on the night, in the run up to the event, it seemed like the elements were conspiring against us – with thunder, lightning and hail during the tech rehearsal on the Friday night, and torrential rain and flooding during the dress rehearsal on the Saturday night! Fortunately, the day of the concert itself was lovely and the event was able to take place with no hiccups.

Here are some behind the scenes pictures giving an exclusive peek into what it took to get our tree looking like it did on the night!

(read the captions for the full story)

The lighting ‘rig’ began a week before on Monday 1 May – when the specialist lighting company Ithaca arrived on site, assisted by a cherry picker and tree climbers to begin the installation of 12,500 lights Click for information
This was followed by lighting, cables and specialist equipment and 24 eco bikes which were ridden by students and Garden volunteers to power up the lights on the tree. Click for information
A crew of around 30 people were on site all weekend, setting up for the event. This included a satellite truck where the director and his assistant liaised with the BBC team in Windsor and directed the cameras on location to get the shots which were broadcast across the world. Click for information
A remote-controlled high tech robot camera on wheels was set up to run through the line of cyclists and up to the tree before cutting to a static camera shot showing the tree in all its glory as well as the backdrop of the Garden’s Main Walk. Click for information
And it looked stunning! Click for information

It all sounds simple – but the reality was quite different!! Here’s a behind the scene glimpse at what when on behind the cameras/what you didn’t see!

Heavy rain on Saturday impeded efforts. Equipment had to be kept dry and the entire crew and cyclists got drenched! Click for information
Rehearsals continued in heavy downpours; Garden staff used brooms and buckets to empty the Main Walk of water which impeded cycling and filming and the cyclists continued to pedal so the BBC’s Director could rehearse camera shots and show the Windsor team how the set looked in reality. Click for information
Thankfully the sun shone on Sunday and all went according to plan! Rehearsals took place from 6pm with the Director, crew and cyclists rehearsing camera shots and sharing them with the Windsor team. Click for information
As it got dark, the concert began and was played out on loud speakers to the cyclists who had to stay on their bikes in case Windsor cut to the location. Click for information
As Paolma Faith walked on stage, the cyclists started to power up the lights and the stunning display on the tree continued for almost 5 minutes. Click for information
Towards the end of the concert, the cyclists powered up the bikes and tree again during Take That’s concert finale, just in case Windsor cut to the set for a final glimpse of the pedal-powered display. Click for information
It’s a wrap – at 10pm the cyclists went home and then the crew worked late into the night to derig the set. It was a sometimes challenging, but incredibly rewarding event and everyone at the Garden was thrilled to be part of such a landmark celebration. Click for information
