The funeral for former heavyweight boxing champ Joe Frazier, who died on Nov. 7 after an almost two-month battle with advanced stage liver cancer, took place Monday with many -- family, friends, celebs and those in the boxing community -- paying their condolences in what turned out to be a service that lasted over two hours at the Enon Tabernacle Baptist church in Philadelphia, Pa.

The most iconic moment in the proceedings came when Frazier's greatest opponent and boxing legend Muhammad Ali stood up and vigorously clapped for his fallen rival. Wearing a dark suit and sunglasses, Ali held hands for assistance in and out of the Baptist church.

Frazier, known as Smokin' Joe, rose to boxing preeminence in the late 1960s, defeating a string of opponents and becoming the undisputed heavyweight champion in 1970. He lost his title in 1973 when he was defeated by George Foreman and later lost to Ali in two rematches. Frazier retired in 1976 after losing once again to Foreman, making a brief comeback in 1981. He finished with a 32-4-1 record, having lost only to Foreman and Ali.

Besides Ali, former heavyweight champion Larry Holmes and promoter Don King also paid respects at the private funeral. The Rev. Jesse Jackson made remarks and Mike Tyson, Donald Trump and actor Mickey Rourke sent videotaped messages of condolences.
