Officer McNulty told Today that singing has been a huge part of the life of him as well as his fellow officer, Tavares.

He was a part of an acapella group for several years before retiring from the entertainment industry and pursuing his dream of becoming a police officer like his father and a brother.

Tavares is also a songwriter who enjoys singing during her free time with local bands. The two police officers have separately performed on behalf of the Boston police department at several events all around the city.

"We have both performed the national anthem on behalf of the BPD at events all around the city, but had never sung a duet," McNulty further told Today through an email.

The duet they sang in the YouTube video was their first one, and the pair proved that it was worth all the wait.

"With the stress that we have to go through on a day-to-day basis, you need something that levels that stress out and music, it just makes you happy," Tavares added in his interview.
