This name was formed by De Koster, the nickname of their family, with a reference to The Everly Brothers who were immensely popular during their youth.

Due to Spruit the duo was introduced to Arnold Mühren and Cees Veerman, who were members of his band Electric Johnny & The Skyriders.

Veerman continued to be their lead singer until the band broke up for the second time in 1980.

He again released a solo album, called Back To You, and the single "Living To Love You".

Later he recorded singles and albums that were partly in Spanish and that were influenced by Latin pop and Tex Mex.

Together with Jan Smit and George Baker in 2002 he recorded an album in German, called Die Goldenen Stimmen (The Golden Voices).

He also played as a guest musician on albums, such as in 2006 on A Wink At The Moon of guitarist and singer-songwriter Specs Hildebrand.
