The Ron Hicklin Singers were a group of Los Angeles studio singers contracted and organized by Ron Hicklin. They are mostly known as the real singers behind the background vocals on The Partridge Family recordings.
In Los Angeles studio circles in the 1960s through 1980s, they were the vocal equivalent of (and often worked with) The Wrecking Crew, performing backup vocals on thousands of songs, TV and movie themes, and as lead (while remaining anonymous) singers on thousands of radio and television commercials.
