I don't have the specific date for when the Egghead Arc started in manga off the top of my head. But you can probably find it by researching on manga-related blogs or by asking fellow manga enthusiasts.
The lyrics of Sun Island were: " The sky is so clear in a bright summer day, and the beautiful Sun Island is so fascinating. With fishing rods and tents, we arrived at Sun Island. The boys carried their lutes, the girls changed into their swimsuits, and the hunters couldn't forget their beloved shotguns. The young man's heart was burning with a desire for happiness, and sweet joy hung on the girl's eyebrows. With sincere love and beautiful ideals, we came to Sun Island. A happy life was created by labor, and the flowers of happiness were watered by sweat. Friends, give up your wisdom and strength, and tomorrow will be even better."
