Q: Buenos Aires, Argentina (CNN) -- Roberto Sanchez, the Argentine singer known as "Sandro" and who drew comparisons to Elvis Presley, died Monday night after complications from surgery, his doctor told reporters. He was 64.

Sandro's romantic ballads made him a star in the 1960s, but he first found the limelight as rock and roll singer who imitated Elvis' style.

In his long career, Sandro recorded dozens of albums and also acted in 16 movies, according to the Web site Rock.com.ar. He is considered one of the pioneers of the Spanish Rock movement.

The singer was also known as "El Gitano," or "the Gypsy," because of his family's Roma roots.

Some accounts place Sandro as the first Latino artist to sell out Madison Square Garden in New York.

Sandro died at the Italian Hospital in Mendoza, Argentina, where he was being treated for complications from a heart and lung transplant last month.

He is survived by his wife, Olga Garaventa.

Funeral arrangements are pending.

Q: Dakar, Senegal (CNN) -- Polls closed Sunday in Senegal where citizens voted in an election overshadowed by violence as protesters demand the elderly president refrain from seeking another term.

President Abdoulaye Wade, 85, was booed and jeered when he cast his ballot at a polling station in the middle-class neighborhood of Point E. He did not address the crowd, looked visibly frustrated at one point, and made some sort of gesture to the crowd, which also included some of his supporters.

If a candidate does not win 50% of the vote, a runoff election will be held next month in the West African nation.

"We've had enough of this regime of thieves and assassins. We will defeat them here," said Cheikh Gassama, a voter at the Point E station. As the president arrived, he and other chanted "Na Dem," which means "step down" in Senegal's predominant Wolof language.

Senegal is one of the continent's most stable democracies. Past elections have included a smooth transition of power, a rarity in a region with a history of election chaos, civil wars and coups.

Turnout on Sunday was low, according to Thijs Berman, chief observer of the European Union monitoring mission.

"Early in the morning, you saw long queues of people in front of polling stations but, later in the day, there were much less people and it seems that the turnout is below 50%," he said. "There was high political tension before these elections, so it is surprising that so few people came to vote."

Q: (CNN) -- Branden Grace stepped up his bid for back-to-back tournament wins by taking a four-shot lead at the halfway stage of the Volvo Golf Champions tournament at The Links at Fancourt Friday.

The 23-year-old South African carded a seven-under-par 66 to set the pace on 12-under 134 after two rounds.

Compatriot Thomas Aiken, who shot 70, and England's Lee Slattery, who raced up the field with a best-of-the-day 65, are his nearest challengers.

European Ryder Cup captain Jose Maria Olazabal of Spain showed he is still a force at 45 with an impressive 68 to be alone on fourth on 139.

Grace only received an invitation to the 35-strong champions-only field by winning last week's Joburg Open and has seized his opportunity in fine style.

He was paired with first round leader Nicolas Colsaerts of Belgium, who crashed to a 76 to fall six shots off the pace.

Home favorite Ernie Els, fellow three-time major winner Padraig Harrington of Ireland and reigning British Open champion Darren Clarke of Northern Ireland are eight shots off the blistering pace being set by Grace.

Meanwhile, Colombia's Camilo Villegas and David Toms of the United Stages led after the first round of the PGA Tour's $5.6 million Humana Challenge in California.

Villegas carded his nine-under 63 on the Nicklaus Private Course and Toms matched him at La Quinta Country Club.

South Korean rooke Bae Sang-moon was in the chasing group on 64 with Ted Potter, Brandt Snedeker and Bob Estes.

Toms played with star attraction Phil Mickelson, who struggled to a two-over 74 after a triple-bogey seven at the par-four 14th, on the toughest of the three courses used for the tournament.
