Peter Ostroushko, a world-class musician who has been part of the Twin Cities scene since the 1970s, is having all kinds of health issues. First, there was the heart attack in December and ensuing bypass surgery, and then a stroke in January while he was in a doctor's office.

Many of Ostroushko's musical friends will join together to perform a benefit Sunday for the widely respected fiddler/mandolinist who played for many years on "A Prairie Home Companion" and has released a series of outstanding recordings, many on the Red House label. Among his many credits: He played on Bob Dylan's "Blood on the Tracks" album, performed with the Minnesota Orchestra and St. Paul Chamber Orchestra, and contributed music to Ken Burns' documentaries.

The benefit is at St. Joan of Arc Catholic Church in Minneapolis with Peter Yarrow of Peter, Paul & Mary as the headliner.

The lineup sounds like a who's who of the Twin Cities acoustic scene, including Dakota Dave Hull, Greg Brown, Dean Magraw, Ann Reed, Mary DuShane, Becky Thompson and Daithi Sproule plus actor/writer Kevin Kling. Radio personality Dale Connelly will serve as emcee.

True to Minnesota style, the event starts with a potluck dinner at 5 p.m. Sunday. Music begins at 7 p.m.

Admission is $25. Donations are also being accepted at gofundme.com/peter-and-marge.
