As Peachtree Elementary School students headed to their buses on Monday afternoon, they marched through a sea of bubbles to the tune or an arguably fitting anthem for the 50th anniversary of the school’s opening.

The school picked a ’70s theme for celebrations of five decades of learning at the Peachtree Elementary, which opened in 1971. As part of that theme, the Jackson 5’s “ABC” was blaring out of a sound system as the students headed to their buses.
