Sandra Kerr says; "I am part of 'The Anti-Capitalist Roadshow' which is a collective of singers and songwriters: Frankie Armstrong, Roy Bailey, Robb Johnson, Reem Kelani, Grace Petrie, Leon Rosselson, Janet Russell, Peggy Seeger, Jim Woodland plus one socialist magician, Ian Saville.

We are part of another way of looking at the world."
