1967/68: The ‘Yellow Submarine’ nickname is Born
The nickname the ‘Yellow Submarine’ was born after the song was released by the Beatles in 1966. In the 1967/68 season, the club was fighting for promotion to the Third Division (Tercera División) once again, which they eventually achieved in that campaign. Meanwhile, a group of young fans started to play this Beatles song on a battery powered record player during matches. And they sang it with their own lyrics: "Amarillo el Submarino es / amarillo es / amarillo es" ("The Submarine is yellow / it is yellow / it is yellow”).
With the passing of the years the Villarreal CF kit changed to yellow shirt and blue shorts. It wasn’t until the ‘Golden Age’ of the club, when the Yellows were the elite of national and international football (2004/05), that the club decided to wear all yellow, including the socks, in honour of the nickname.
