The song "Sky-Bo" by Merle Haggard tells the story of a new type of traveler, the sky-bo, who travels the world by airplane. The term "sky-bo" is a play on words, combining the words "sky" and "hobo", which refers to the old-fashioned travelers who often traveled by train. The lyrics describe the life of a sky-bo, who takes a job as a pilot, flying wealthy people around. However, he soon gets tired of the same routine and decides to catch a flight to a new destination. He spends his time traveling from airport to airport, always in search of the next adventure. The song also highlights the struggles of a sky-bo, who often finds himself alone in crowded airports, with no place to go. However, he remains resilient and determined, always looking for his next flight to the next destination. Overall, "Sky-Bo" is a song about the wanderlust and adventurous spirit of a unique type of traveler, who lives for the thrill of exploring new places and seeing the world from above.
