The world lost renowned Canadian folk singer Kate McGarrigle on Monday, after she lost her three-year battle with sarcoma, a rare form of cancer that affects connective tissue.

McGarrigle was most famous for performing with her sister Anna as the McGarrigle Sisters, whose hits included “Heart Like a Wheel,” and was the mother of musicians Rufus Wainright and Martha Wainright, whom she had with her ex-husband Loudon Wainright III.
