Former Utahn and Idaho's first lady of song - Rosalie Sorrels - has suffered a cerebral aneurysm and is expected to undergo surgery next week.

Sorrels, known internationally for her gravelly voice and casual performances, was in serious condition in St. Alphonsus Regional Medical Center Thursday night.Family spokeswoman Jean Terra, who has worked with her on the Idaho Folk Song Project, said Sorrels was sedated but able to converse with her family.

Sorrels, 55, was diagnosed as having a cerebral aneurysm - a weakness in a blood vessel in the brain that can damage the tissue.

Sorrels, who lives on Grimes Creek near Idaho City, had recently returned from Fort Hall Indian Reservation, where she was collecting stories and songs for the Idaho Songbook for the state's centennial in 1990.

Sorrels, was born and reared in Idaho, but had also lived and performed in Utah. After her marriage broke up, in 1966 she hit the road with her five children, making her living singing folk songs in coffee shops and clubs.

She has been a crusader for unpopular causes ever since the mid-'50s when she spoke out against nuclear testing in Utah and Nevada.
