A pilot event that saw about 3,000 club-goers return to the dancefloor has been hailed as a glimpse of what the future might hold by public health leaders.
Liverpool director of public health Matt Ashton said it was "wonderful" to see the looks on people's faces at The First Dance, hosted by club night Circus, in the city on Friday.
Attendees, who all had to produce negative coronavirus tests, did not have to wear face coverings or social distance for the first time since before lockdown began.
It is hoped the event, the first of two taking place on consecutive nights, will pave the way for clubs across the country to reopen their doors.
Mr Ashton told BBC Breakfast on Saturday that the event gave a glimpse of what the future might hold but stressed it was still a scientific experiment about how more events could be opened in the future.
He added: “This is a scientific experiment, both before and after the event people have to return to doing the things they are supposed to, so following the rules in place.
“We have to deal with Covid still as if it is still around because it is, even if it is at low levels, so we have to be cautious in our approach. And for me that’s why it is so important that we collect the science around this to allow us to do this safely and properly in the future.
“But it is still wonderful to see the looks on people’s faces as they were at the event last night. It just gives a glimpse of what think we think the future might hold.”
When asked if the data from the pilots will be crucial to opening up society again in late June, Mr Ashton said: “Yeah, don’t forget this is a crucial part of our economy, in Liverpool it’s over 40 per cent of our economic output, so it’s really important we start to get the economy opening again.
“But also just in terms of a return to normal life, all of us being social creatures and doing the things we want to do more.
“So the evidence base is absolutely essential.
“This is going to be part I think of a longer journey of understanding how we live with Covid more safely in the future.”
Inside the Bramley-Moore Dock warehouse, crowds packed the floor to dance shoulder-to-shoulder for the first time in more than a year.
Club-goers were seen hugging and kissing each other, with some sitting on others’ shoulders for a better view of the stage.
In the queue outside the venue, Liverpool University student Elliott Cause (20) said: “I feel like this is a big moment for the UK.
“I feel like uni students have been struggling without this, I feel like this will do a lot.
“You can already see people are so up for it, the energy’s great.”
The line-up for Friday included Circus founder and DJ Yousef, Lewis Boardman and The Blessed Madonna.
Fatboy Slim is among the acts due to perform on Saturday.
Sam Newson, the event producer, said the pilot was "vital" after the events industry had been "decimated" over the last year.
He said: “For the last 12 months, it has been a disaster.
“People have moved on, I’ve got colleagues who have lost houses, it has been incredibly hard and so to try and get this back up and running is incredibly important.”
He added: “I stood on stage early on and I had a little bit of a teary eye, I’m not going to lie, it is very emotional.
“Any event is special but with the amount of work that has gone into this and to be the first in the country in over 12 months, it is very special.”
Scientists will be looking to see whether crowds mixing and dancing indoors increases the risk of transmission of Covid-19.
Air quality and movement was also being monitored as part of a Loughborough University-led study to create clear guidance on how to design and operate non-domestic buildings to minimise risk.
The night is part of the Events Research Programme, which will also see crowds return to events including the FA Cup final and a music festival held in Liverpool’s Sefton Park. – PA
