Muhammad Ali's funeral and memorial service Friday drew more than 100,000 people to the streets of Louisville, the hometown of the former heavyweight boxing champion who died last week at age 74.
After a private funeral for Ali at Louisville's Cave Hill Cemetery, the procession moved to the KFC Yum Center, site of a memorial service featuring celebrities and politicians from around the world -- gathered to celebrate "The Greatest."
The start of Ali's memorial service was running a little more than an hour late. A simple stage in the KFC Yum Center featured flowers as well as the U.S. and Olympic flags.
Former President Bill Clinton accompanied Ali's widow Lonnie into the arena, and the service began with Muslim prayers.
Earlier, chants of "Ali!, Ali!, Ali!" from onlookers greeted Ali's casket as it was moved in the funeral procession. Crowds in downtown Louisville shouted "We love you," as the procession made its way to the site of today's service.
The larger-than-life Ali is drawing fans, famous and anonymous, to his service. Former boxing champion Mike Tyson was a late addition as a pallbearer for the burial.
Other notable expected to attend the memorial service include comedian Billy Crystal, TV journalist Bryant Gumbel and the champion's wife, Lonnie.
From around the world, Jordan's king and Turkey's president are also expected to attend.
It has been reported that President Obama was unable to make the trip because his daughter, Malia, is graduating from high school. Valerie Jarrett, a senior White House adviser, is to read a letter Obama wrote to Ali's family at the service.
As many as 15,000 people are expected to attend the service.
The Associated Press reported that there will be the single word inscribed on the headstone for the boxing superstar.
Family spokesman Bob Gunnell told the AP the simple stone is in keeping with Islamic tradition.
Ali chose Cave Hill Cemetery as his final resting place a decade ago. Cave Hill is on the National Register of Historic Places, and also the final resting place of Kentucky Fried Chicken founder Colonel Harland Sanders.
Ali wanted to be buried in his hometown, where he learned to box and fought his first fight. He also built a museum and the city named a street in his honor.
The AP also reported that people gathered early outside Muhammad Ali's boyhood home in Louisville, which was decorated with balloons, flags, flowers and posters for Friday's memorial.
A procession with Ali's casket was to pass by the home Friday morning.
Fans took photos of themselves standing in front of the small pink home with white trim, and standing near a large cloth poster on the lawn decorated with images of Ali, and declaring him "The Greatest."
Some people staked out their place near the home with lawn chairs. Others milled about on foot.
On Thursday, more than 14,000 joined together for a Muslim prayer service that begins two days of memorials for Muhammad Ali.
The brief service, which is part of a plan designed by Ali himself years before he died, began with a message of inclusion from the imam leading it. Read about Thursday's events here.
"We welcome the Muslims, we welcome the members of other faith communities, we welcome the law enforcement community," Imam Zaid Shakir, a prominent U.S. Muslim scholar, told the crowd. "We welcome our sisters, our elders, our youngsters."
Our Brian Schmitz wrote today about meeting Ali on an airplane and noting, " Ali might be the only man who could board a plane today and hand out Islam literature without feeling a backlash."
Schmitz wrote: "After greeting the flight crew and shaking hands, Ali headed straight for me, he and his wife, Lonnie, taking the seats on the adjacent row.
