Firefighters sing ‘Let It Go’ to scared girl stuck in elevator

The song "Let It Go" from Disney's Frozen has had some pretty incredible (and adorable) covers. This latest version, however, is the first we've heard of to help bring anyone to safety.

Late Wednesday afternoon, Reading, Massachusetts firefighters John Keough and Scott Myette rescued 4-year-old Kaelyn Kerr, her mother, Kristen Kerr, and her baby brother from an elevator with a jammed door — with a little help from Disney.

The only way to free the trapped family was to help them climb a ladder out the top of the elevator car and over a wall.

"When they put the ladder down that's when she kind of started freaking out a little bit," Kristin Kerr recalled Kaelyn's anxiety.

So the firefighters, both fathers of young children, put their parenting skills to good use — and serenaded scared 4-year-old Kaelyn Kerr with her favourite song.

Myette found "Let It Go" on his phone. He and his partner starting singing along, hoping to calm her down.

"It worked," Keough told MyFoxBoston. "We got her to a point where she was comfortable with us and up the ladder we went, right up and over, no problem."

"You say, okay how would my kids be comforted in this situation, so anything we can do to make them more comfortable makes our job a lot easier," Myette said.

About thirty minutes after getting stuck in the elevator, the family of three got out safely.
