For Wainwright's new album was written during the final throes of his mother Kate McGarrigle's life and tonight's performance is a dedication to her life.
Wainwright and McGarrigle's two children, singers Rufus Wainwright and Martha Wainwright, lend their vocals to the Poole tribute album, High Wide and Handsome: The Charlie Poole Project.
One album I completely missed when it came out last year was the self-titled debut release from Martha Wainwright, the sister of cabaret-pop singer Rufus Wainwright and daughter of folk artists Loudon Wainwright and Kate McGarrigle.
