#22: The Gilligan’s Island Theme Swapped Singers Mid-Voyage
The first season’s iconic theme song was sung by a folk trio called The Wellingtons, whose upbeat harmonies helped launch the castaways’ story each week. Their lively sound fit the show perfectly, giving the opening a bouncy, folksy charm that fans still hum today.

But after season one, the studio switched to another group with a nearly identical vibe: The Eligibles. Most viewers never noticed the change, since the new singers matched the original style closely. It’s a fun little musical shuffle that shows how even theme songs sometimes get recast behind the scenes.
