From CNN's website:

SUMMERLAND KEY, Florida (AP) -- Folk singer Fred Neil, who had such hits as "Everybody's Talkin' " and "Candy Man," was found dead Saturday of natural causes in his home. He was 64.

Neil started his music career in 1955 when he moved from St. Petersburg to Memphis, Tenn. He released his first single, "You Ain't Treatin' Me Right/Don't Put the Blame On Me," two years later.

The singer became a cult favorite in New York City's Greenwich Village folk scene after Roy Orbison released a blues recording of Neil's "Candy Man" in 1960.

Neil released his first solo album, "Bleecker & MacDougal," in 1965. After moving back to Florida, Neil took an interest in protecting dolphins. He frequently visited Kathy, the star of the television show "Flipper," and wrote a song called "The Dolphins," which was released on his 1967 album "Fred Neil." Billy Bragg delivered a haunting cover of the song on his 1991 album, "Don't Try This at Home."

In 1970, Neil co-founded the Dolphin Research Project to help curb the capture and exploitation of dolphins worldwide.

His last big hit came in 1969 when the film "Midnight Cowboy" featured singer Harry Nilsson's version of Neil's "Everybody's Talkin'."
