The first May Day Olympic festival of 1931 was held in Edmund Lyon Park behind the high school. The program included the coronation of a king and queen, musical entertainment and interclass athletic events. Four tents were set up for the classes — green for the freshmen, red of the sophomores, orange for the junior class and blue for the seniors. The first high school yearbook was also produced that year. It was called the Gagashoan, a word believed to mean tales told by a Native American storyteller.
In 1940, a new tradition was added to the May events — a class day with a song contest among the high school classes. Started by music teacher Dorothy White, each class sang a song about its achievements to the senior class. Lyrics were written by the students, with the music being a current tune. The winning class was given a trophy. The classes also sang farewell songs to the senior class.
School newspaper articles describe the 1950s as a time of transition. For much of the decade events were held on two different days. Often the coronation ceremony and entertainment were held on a Friday evening, with a dance in the gym afterwards. Moving Up Day was a separate day with the song contest, senior entertainment and the actual moving up of classes to different seating in the auditorium. A tradition of handing over the responsibilities of leadership from the senior class president to the junior class president was also described—the Spade Oration.
By the 1960s, the coronation and Moving Up Day ceremonies were held on a Friday afternoon in June. The ceremonies began with the viewing of the king and queen and their court, freshman continued to wear green, sophomores red, juniors blue, and seniors dressed up. The spade oration took place. Classes continued to move up to new seats in the auditorium. Songs were sung in honor of the seniors and the song contest took place, with senior entertainment following. Yearbooks were distributed at the end of the afternoon.
By the 1970s, the Moving Up Day ceremonies were held on a Friday morning with interclass athletic games and a picnic in the afternoon. The Gagashoans were given at the end of the day. This tradition continues. For high school students, the day remains a special concluding memory of their school years.
