Organizers expected up to 1 million people at the Bola Preta street party, or "bloco"
- one of Rio's oldest. Dressed in black and white, the revelers lustily sang along to traditional Carnival songs like Rio's anthem, "Cidade Maravilosa"
- "The Marvelous City."
"I got up early to get here because this bloco is a monument to Brazilians' ability to show the world complete happiness," said Clandecy Claudio, a 23-year-old truck driver sporting a T-shirt that read "Beer Is Good For You" and with a can of the beverage in each fist. "For a few days I can let my work go and forget all my troubles."
In the northeastern city of Salvador, which battles Rio each year for bragging rights to the nation's wildest Carnival, police said thousands of people had simply collapsed in public plazas to catch a few hours of sleep after partying all night.
Even sober Sao Paulo, Brazil's business capital, showed its partying colors, holding its first night of flamboyant samba group parades. Brazil's brutal sun was shining hard by the time the last dancers left the street.
But it's Rio's massive fest that draws the most attention - and international celebrities. Madonna, Beyonce, the Lindsay Lohan and Paris Hilton were all expected to watch as Rio's samba parades begin Sunday night.
But the essence of Rio's Carnival is in its street parties, which have regained popularity in recent years.
Thousands danced to a samba beat on the cobbled streets of the bohemian Santa Teresa neighborhood Friday evening, donning skimpy costumes bordering on blasphemous.
At the "Carmelitas" party - named after a nearby convent - groups of young women dressed as sexy police in cutoffs and tank tops, while grown men donned baby outfits, sucked on pacifiers and showered themselves with talcum powder.
