In late 1972, Winter brought together Dan Hartman, Ronnie Montrose and Chuck Ruff to form The Edgar Winter Group, who created such hits as the number one "Frankenstein" and "Free Ride" (with lead vocals by its writer Hartman). Released in November 1972, "They Only Come Out at Night", peaked at the number 3 position on the Billboard Hot 200 and stayed on the charts for 80 weeks. It was certified gold in April 1973 by the RIAA, and double platinum in November 1986.
