On April 29th, students, staff and administration at Lower Merion High School flooded the school's hallways to film a school-wide lip dub to the song "Firework" by Katy Perry.

As part of the school's continued efforts to fight cancer, the lip dub was put on to promote an end-of-year online giving campaign for the American Cancer Society's Coaches vs. Cancer program.

"We're a school that tries to do a lot of fundraising and we're always looking for fun ideas to make that happen," said Principal Sean Hughes. "We saw two similar lip dub videos that really piqued our interest and we decided to put something together to get the whole school involved."

Previously, the school's Coaches vs. Cancer committee has raised funds through events like dance-a-thons, dodge ball and 3 on 3 basketball tournaments — but this year's school-wide lip dub definitely takes the cake.

"A group of students worked with our Coaches vs. Cancer committee to put everything together," said Hughes. "They picked the song, mapped out the routes and some of the kids were coming in at 6:30 a.m. to make this happen — so I have to give a lot of kuddos to the kids."

The video has been viewed more than 7,500 times since it was posted last week.

According to the school's fundraising page:

"Cancer is a fierce opponent, but our team is committed to helping the American Cancer Society raise awareness about what we can do, together, to help end this disease.  Our mission is clear – keep fighting for the day when no one hears the words "you have cancer."

So far, the Lower Merion team has raised $3,502 for the American Cancer Society, not far from their $5,000 goal.
