Dana first came to the attention of then public In 1970 she became the first Irish winner of the Eurovision Song Contest with the ballad 'All Kinds of Everything'.
The song reached number one in the pop charts of several countries and sold over a million copies worldwide.
She continued to have a successful career as a singer before moving to the US in the 80's where she worked as a broadcaster with Eternal World Television.
In 1997 she entered politics in Ireland, contesting the presidential election of that year, an election won by Mary McAleese. Dana Rosemary Scallon, as she is now known, later represented the Connacht Ulster constituency in the European parliament.
She has recently been seen on The Afternoon Show and as a subject of Class Reunion on RTE.
Dana's style of cooking has been honed in the family home where, she maintains, her children had a tendency to be 'fussy eaters'.
The family are all pretty much grown up now and Dana can take the time to cook what she likes herself. Her vegetable soup has been called into service for this edition of The Restaurant. When asked for the recipe Dana replied, "I'm not entirely sure, as every time I do it, I put different things into it."
An adventurous approach which, she hopes, will pay off with a high star rating from the critic's table. Will Dana's menu be a chart topping hit, or will it be a mish mash of 'All Kinds of Everything'? Find out in The Restaurant
