No cause of death was announced, although multiple reports say he had been ill for some time.

He received two Oscars for co-writing the iconic themes for “Titanic” — which was recorded by Celine Dion — and for “An Officer and a Gentleman” alongside Jack Nitzsche and Buffy Sainte-Marie.

He won a Golden Globe for best original song and Grammys for record of the year and song of the year for “Tears in Heaven” — performed by Clapton” — from the movie “Rush.”

Jennings was inducted into the Songwriters Hall of Fame in 2006.

Musician Peter Wolf paid tribute to the lyricist in a social media post, writing, “‘A Lot of Good Ones Gone’ … A sad time, the passing of Will Jennings, a maestro, brilliant mind and a gentle spirit. Will shared his talents with me, ever patient and generous, he was a treasured friend and teacher, enriching my life in so many ways. It was an enormous honor to have worked with such a musical genius for so many years …To quote one of his favorite poets, W.B Yeats,’Think where man’s glory most begins and ends, and say my glory was I had such friends.'”

Jennings is survived by his wife, Carole, and his sisters, Joyce and Gloria.
