Live from Abu Dhabi Connect the World takes you on a journey across continents, investigating the stories that are changing our world.
The fall of the Berlin Wall on November 9, 1989 heralded the fall of communism in Europe and ultimately the end of the Cold War between the West and the Soviet Union.
Overnight the world changed. Suddenly the people of eastern Europe were able to travel freely. Many of the former countries of the Soviet bloc eventually joined the European Union and Nato, something that would have been unimaginable before the Wall fell.
While all this has meant the threat of imminent nuclear war in Europe is over, many remain nostalgic for the strict certainties of the old regimes, when a job for life was common despite economic deprivation. Reunification of Germany has also proved to be easier said than done while many point to resurgent nationalism in the former Soviet bloc as a worrying trend.
We want you to share your memories and to hear your comments. Tell us where you were when the Wall fell. Do you think the world is a better place now? How has it changed and have lessons been learned? We will try to use as many comments as possible on tonight's Connect the World show.
Dolly Parton introduced herself to the country music charts in 1967, at the age of 21, with her debut album "Hello, I'm Dolly."
A successful partnership with Porter Wagoner, the host of the television show of the same name, put her on the national stage.
Forty albums have followed, including a succession of No. 1 hits, awards and high-profile performances on television and film.
She's almost as famous for her image as her vast array of hits. Striking sculptured hair, bright lashings of eye shadow caked on a face that she has admitted in the past owes a lot to modern surgery, and always very high heels.
In 1986, Parton's megastar status was confirmed with the opening of her own theme park "Dollywood." In 2001, a water park, "Dollywood's Splash Country," opened next door.
If you've got any comments on the country singer with four decades of performing behind her - and still going strong - have your say here.
