Mexico City, Feb 11 (IANS/EFE): With a combination of catchy numbers and a great deal of energy, Chayanne and Marc Anthony got the more than 100,000 people attending their free concert in the Zocalo, Mexico City's main plaza, up and dancing on the weekend.

Dressed in black and wearing sunglasses, Anthony took the stage first to the beat of his hit "Valio la pena", which got the mainly female crowd going after waiting for hours for the concert to kick off on the huge plaza Saturday.

This is the first concert held under Mexico City Mayor Miguel Angel Mancera, who is following the lead of his predecessor, Marcelo Ebrard, in fostering huge - and free - cultural events organized in the Zocalo in a country where having to pay to go to a concert is not within everyone's financial grasp.

Anthony was on stage for an hour and said he was very impressed to be able to perform there.

"I've seen a lot of things in my life, but this is incredible," the 44-year-old singer said.

Then Chayanne came on stage, also dressed in black and wearing a tight T-shirt, to sing his number "Boom, Boom", accompanied by a group of dancers.
