The club won the European Cup for a sixth time in 1966 defeating Partizan Belgrade 2–1 in the final with a team composed entirely of same nationality players, a first in the competition. This team became known as the Yé-yé. The name "Yé-yé" came from the "Yeah, yeah, yeah" chorus in The Beatles' song "She Loves You" after four members of the team posed for "Marca" and impersonated the Beatles. The Yé-yé generation was also European Cup runners-up in 1962 and 1964. In the 1970s, Real Madrid won five league championships and three Spanish Cups. The club played its first UEFA Cup Winners' Cup final in 1971 and lost to English side Chelsea 2–1. On 2 July 1978, club president Santiago Bernabéu died while the World Cup was being played in Argentina. FIFA decreed three days of mourning to honour him during the tournament. The following year, the club organized the first edition of the Trofeo Santiago Bernabéu in memory of its former president.
