[1] During the summer, Jean and part of the crew of El Hormiguero held castings in different points of Spain to scout for potential band members.
By the time the next season of the show started in September, the castings were finished and the finalists appeared on El Hormiguero for live auditions.
The band was completed on October 29, 2013, when Alberto Ladrón de Guevara was selected as the fifth member.
[2] The name of the band was also selected via Twitter, and it was announced live on the November 11, 2013 episode of El Hormiguero by the night's special guests Backstreet Boys, just moments before Why Five's first live performance, in which they debuted their first single, Going Up.
Later that month, Alberto confirmed via Twitter that he had dropped out of the band too in order to pursue a solo career.
