You will raise money for the safe return of Alison and Jenny McGregor. If you raise enough money within fourteen days they will be released. If not, Jenny will be killed.
Alison and Jenny McGregor—Aberdeen's own mother-daughter singing sensation—are through to the semi-finals of TV smash-hit Britain's Next Big Star.
