 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.

Santiago's diabetes started taking a toll on his health during the 1990s.
