Though they have the same name as a Four Freshmen-style pop vocal group of the 1950s (best known for singing backup with Elvis Presley on several film soundtracks and for their bass singer, Thurl Ravenscroft, who went on to sing "You're a Mean One, Mr. Grinch"), the Swedish group called the Mellowmen take their musical cues from a different era. Echoes of AM radio circa 1967-1977 percolate through the Mellowmen's music, from the Beatles and Wings through Elton John, Neil Diamond, Electric Light Orchestra, and countless beloved one-hit wonders.
