Neil Young has filed for divorce from Pegi Young, his wife of 36 years. Rolling Stone reports that the legendary singer-songwriter filed a petition for dissolution of marriage in their hometown of San Mateo, CA. The magazine also claims that a hearing is scheduled for December 12.

Young first met Pegi, who also performs with her own band The Survivors and has collaborated with her husband on numerous occasions, while she was working as a waitress near his California ranch. The story of their introduction is outlined in Young’s 1992 song “Unknown Legend,” one of many songs inspired by Pegi.

In addition to their musical collaborations, Neil and Pegi Young also co-founded The Bridge School together in 1986. The pair have funded the school, which provides education for students with severe physical impairments, with an annual, star-studded benefit concert.

Both Neil and Pegi are scheduled to perform at the upcoming Farm Aid concert in Raleigh, NC on September 13.
