Raymond Thomas was an English musician, singer and songwriter. He was best known as a founding member of the English progressive rock band the Moody Blues. His flute solo on the band's 1967 hit single "Nights in White Satin" is regarded as one of progressive rock's defining moments. In 2018, he was posthumously inducted into the Rock and Roll Hall of Fame as a member of the Moody Blues.

"It Ain't Necessarily So" is a popular song with music by George Gershwin and lyrics by his brother Ira Gershwin. The song comes from the Gershwins' opera Porgy and Bess (1935) where it is sung by the character Sportin' Life, a drug dealer, who expresses his doubt about several statements in the Bible. The song's melody also functions as a theme for Sportin' Life's character.
