The theme comes from the Spider-Man animated series that first aired in 1967, the character's first cartoon adaptation. Written for the opening titles, its lyrics list what the hero can do and its brassy arrangement reflected the pop and jazz styles of the period. The show's long life in reruns and syndication kept the song familiar for decades. Clips later circulated online as a shorthand for old school superhero action, and the melody remains closely linked to early animated Marvel heroes.
