was held at the Tito Puente amphitheater, in San Juan, P.R. by several musicians to celebrate Santiago's musical career. Among the performers were Luisito Carrión, Oscar D'León, Elías Lopes, Andy Montañez, Luis "Perico" Ortíz & Domingo Quiñones. The concert was filmed and released on CD and DVD. In May 2004 Santiago was part of the singers and musical colleagues that participated on a tribute concert dedicated to the 45th anniversary of Tommy Olivencia musical career. Santiago, who adopted Marvin Hagler's "Marvelous" nickname (both because of their common first name and the fact that, at one time, his head was shaved bald like Hagler's), had begun conversations to join a Fania All-Stars comeback as a tribute to Celia Cruz by the summer of 2004, but then, he became severely ill. Death Santiago's diabetes started taking a toll on his health during the 1990s. In October 1996 Santiago had his right leg amputated after having three toes amputated in three separate occasions a few months earlier. He also started having problems with his sight. In November 2002 Santiago suffered two heart attacks followed by a major kidney failure in February 2003. After the kidney failure incident, Santiago had to undergo dialysis treatment. Santiago's name was placed on a waiting list for a kidney transplant but was not able to get a donor. Santiago lost vision from one eye and suffered severe kidney, heart and liver damage on the weeks prior to his death. On the afternoon of October 6, 2004 after many years of health issues, Santiago died at the age of 56 at the San Pablo Hospital in Bayamón, Puerto Rico. His funeral was well attended by the public and music friends, with his brother Billyván playing a Plena tribute to Marvin.

Other artists honored in the square are Rafael Cortijo, Héctor Lavoe, Tommy Olivencia, Tito Puente, Ismael Rivera and Pellín Rodríguez.
