Weekend with Anne Gregg and Peter Windows gives a cheery wave as the children head back to school and looks at some of the subjects they probably will not be studying - the legal facts of life, for example. (And how much do you know about your rights and obligations? Try our quiz and find out on the quiet.) Or join us in an uplifting chorus when Michael Paget revives some spirituals, before COLETTE O'NEIL reads the first of six instalments of A Breath of Border Air by LAVINIA DERWENT , abridged by MYRA BEATON. Produced by the Woman's Hour Unit
