Fifteen thousand Roxette fans traveled from all parts of Bulgaria and neighboring countries to watch Sunday night the Sofia gig of the Swedish duo, Per Gessle and Marie Fredriksson, part of their long-anticipated world tour.

The crowd went wild as Gessle's guitar and Fredriksson's voice were able to produce the same quality of music that they first shared with an adoring world more than 20 years ago.

Perfect Day, Queen of Rain, Spending My Time, How Do You Do, Joyride and of course The Look! brought back cherished memories of the '80s and '90s, when Roxette dominated world music charts.

Other songs like their mega-hit, It Must Have Been Love, which Fredriksson described as their Hollywood song – in reference to it being the title track of blockbuster Pretty Woman – became a sing-along.

Fans in Georgi Asparuhov stadium had to brave the rain and unexpected cold weather, but certainly none was disappointed by the 90-minute show.

After belting out tunes from all their albums, the band left the stage. But the audience wasn't ready to let them go. After two calls for an encore, Gessle and Fredriksson ran back onto the stage and began The Look, followed by Spending My Time and Listen To Your Heart.

The next leg of Roxette tour, the biggest since 1995 and their first world tour since 2002, is the Romanian capital Bucharest, where they will stage a concert on May 30.

The tour kicked off on March 1st in Kazan, Russia and will pass through at least four continents. So far 33 dates in 22 countries in Europe, North and South America and the Middle East until the end of July have been confirmed.

"This is what I have longed and hoped for the whole time since 2002. I am understandably extremely happy to have the opportunity to greet audiences around the world again," singer Marie Fredriksson said in a statement at the end of last year.

Fredriksson was diagnosed with a brain tumor in September 2002, which was later removed in surgery. The tumor was malignant and she endured months of chemotherapy and radiation treatments, receiving some permanent damage to her brain, losing the ability to read and count, the vision in her right eye, and some loss of movement in her right side.
