PHOENIX — The singer of the 1960s hit “Angel Baby,” a song covered by artists such as John Lennon and Linda Ronstadt, has died.

Rose Hamlin, the 71-year-old lead singer of Rosie and the Originals, died in her sleep on March 30, according to a post by her daughter, Debbie Cray, on the late performer’s website.

Hamlin was born Rosalie Hamlin on July 21, 1945, in Oregon. She was raised in Alaska before moving to California when she was a preteen.

Hamlin was 14 years old when she penned “Angel Baby,” a song that Lennon would later call one of his all-time favorites.

Cray said Hamlin hadn’t performed in years over concerns for her health, but she had taken up tending a “lovely garden,” according to her post on the website.
