Set to the tune of "American Pie," "The Saga Begins" recounts the plot of Star Wars Episode I: The Phantom Menace, from Obi-Wan Kenobi's point of view. Yankovic gathered most of the information he needed to write the song from Internetspoilers. Although Lucasfilm declined a request for an advance screening, Yankovic eventually attended a costly pre-screening for charity. He had done such an accurate job with the story line that after the pre-screening, he ended up making only very minor alterations.
McLean not only approved the song but also has said since that his children have played it so much that he has a tendency to accidentally sing Yankovic's lyrics when performing "American Pie" in concert. According to Yankovic's official website, Lucasfilms' official response to the song was, "You should've seen the smile on George Lucas' face." This is the second Star Wars song Weird Al has created, with the first being 1985's "Yoda", a parody of "Lola" by The Kinks.
The video begins in the desert on the planet Tatooine. Yankovic, dressed like Obi-Wan Kenobi, the main protagonist of Episode I walks until he comes across Darth Sidious playing the piano. Yankovic uses the Force to get a resonator guitar, and in the second verse he reappears performing in a Mos Eisley Cantina. In the last verse, he returns to the desert, and in the last chorus, numerous "Obi-Wan" clones sing as a group.
The upper half of the pianist's face is always covered by the hood of the robe that he's wearing much like the Sith Lord Darth Sidious. When asked why, Yankovic stated that, "They didn't want to scare small children," a reference to the playful teasing of Yankovic's pianist, Rubén Valtierra, commonly used in his live shows.
The song was played frequently on Radio Disney and later released on Radio Disney Jams Volume 2. Radio Disney took issue with his line "Do you see him hitting on the queen?" and removed it (so that the song skipped slightly). Yankovic, who usually does not like to change lyrics to suit the needs of others, provided Radio Disney with an updated version, having changed the words to "Do you see him talking to the queen?" He said that the alternate lyrics were preferable to the bad edit.
