Crews put on the finishing touches for the Memorial Day concert on Sunday, but some people were worried about safety and security.
“These are very scary times that we're living in,” Russell Watson, an opera singer, said.
Watson is from the UK and has performed all over the world.
He lives just blocks away from the Manchester Arena, where a deadly explosion happened.
“We heard this colossal bang in the background,” Watson recalled. “It sounded like nothing we'd ever heard before.”
Watson was shocked and angry to hear that more than 20 people died and many others were hurt in a terror attack.
“When you've witnessed something like this where children have lost their lives and been specifically targeted its-- it is very, very sad,” Watson explained. “The response to that -- the human response is 'yeah. I'm not going to let this change my life, but inevitably in some way it will change your lives.”
Watson said he is nervous to perform at the Memorial Day concert on Sunday which is a large event filled with politicians, celebrities, veterans, and everyday American families.
“We are in constant communication and of course paying very close attention these days,” Jill Jackson, who is one of the producers for the Memorial Day concert, said.
The show is working closely with Capitol Police who had security on lock down.
There were barricades, mobile command centers, and swarms of officers around the capitol.
Police set up metal detectors and signs letting people know what they can’t bring inside.
“We take our show very seriously and do everything we can to put it forth on the lawn of the Capitol, but safety is always the first priority,” Jackson said.
Capitol officers monitored national and world events as the concert approached.
“This is about preservation of security, of human beings' lives. So, that little extra weight is worth the time, Watson said.
