AVON, Indiana — Thousands of students from a high school in Indiana perform an epic lip sync — in one take — all for charity.

According to ABC News, students Avon High School performed 68 songs in six minutes — anything from Justin Timberlake and Bruno Mars to Katy Perry and Lorde.

A camera followed the nearly 2,700 students and staff all throughout the school for the video — it’s meant to promote the school’s Riley Dance Marathon, which raised nearly $17,000 last year for Riley Hospital for Children, according to ABC News.

The video took six weeks to plan.
