Bill Bruford, Yes’s original drummer, once described the band as Multi-cultural and Multi-Ethnic… he was not describing the personnel of the band… but the musical influences of the band.

Yes pulled elements, and actual melodies, from Country Music, Jazz, Classical, and were even influenced by American TV themes.

Yours Is No Disgrace, according to Bill Bruford was pulled from the 1960’s America TV show Bonanza.
