The School District of Lancaster community is happy, and they want you to know it.

SDL released a YouTube video last week that features staff and students clapping, dancing and lip syncing to the Pharrell Williams song, "Happy."

McCaskey senior Xavier Gutierrez stars as the main lipsyncer, leading crowds of students dancing through the high school hallways.

The video also features Superintendent Pedro Rivera boogying with Carter MacRae Elementary School students and other scenes from across the district.

SDL first showed the video at its annual all-staff meeting earlier this month. District representative Kelly Burkholder said that meeting sets the tone for an upbeat year, and SDL typically unveils a district video at that time.

GP Film & Photography produced the "Happy" video for $1500. The Lancaster company also created a "Happy" video featuring local leaders and city residents in March.

The SDL video, which you can watch below, has been viewed almost 4,000 times.
