So how do you become famous? And how do you hold on to it? Our special guest Lulu has been in the public eye for over forty years.

Lulu took part in Tuesday's programme - and stayed on afterwards for a special interactive forum on Tuesday. Lulu has had 16 top 40 hits including a collaboration with Take That on Relight My Fire.

She topped the US charts with To Sir With Love at the age of 18 and jointly won the Eurovision Song Contest in 1969 with Boom-Bang-A-Bang.

In her autobiography published this month, Lulu tells her story of how she dealth with the poverty of her early years and the fame which came later on.

Lulu was 'discovered' at a jive club in Glasgow and offered a recording contract. It was the early sixties and the pop boom had just started.

It all began with Shout!, which went on to become her signature tune.

Lulu says she has seen many people destroyed by the pressures of being in the public eye:

Brian Epstein took an overdose. The Beatles fought and broke up, Geprge Best fell back on drink, Karen Carpenter starved herself to death ..I will always remeber Karen. ....None of us realised as we say her wasting away, that she has anorexia. It wasn't a disease that any of us had heard of in the seventies. I admit there are trappings to success. People put themselves out for you. Hard to get theatre tickets are found. Tables at smart restaurants are suddenly available ......at the same time it can be bloody tough to reach the top and stay there. You need to have the hide of an elephant and the love and support of people who will keep your feet on the ground.
