Saturday the 24th marked World Polio Day, and on Sunday Macca received a call from Christine in Fitzroy. In 1954 she and her sister contracted the disease whilst living in Rome. Ian also replays an interview which he recorded with author Kerry Highley, whose book 'Dancing In My Dreams' tells the story of Sister Kenny's pioneering work on a treatment for sufferers of polio.

During a trip to Canberra this week Ian also spoke to Nat Williams at the National Gallery of Australia.

There are also calls from Don in drought-stricken Alligator Creek, and submarine expert Rod from Ballina.
