Holt died Monday morning (England time) from cancer at age 69.
"He will be buried in Jamaica. We are currently in negotiations re getting his body," Gallimore said.
Gallimore, who was also Holt's road manager, said his family is "coping, taking it one day at a time. The 'doc' made it clear there was no hope. For those two days although we were very upset, we had to be strong till the journey is over".
Gallimore recounted the last days of the singer who was diagnosed with colon cancer in June.
"He was at home and doing okay, getting treatment, coming back to himself. Until one day last week," he said.
Gallimore said Holt developed a fever and was taken to hospital where doctors said he had an infection which caused his temperature to rise.
"He was in intensive care for a few days, and started to improve so much so that they moved him to the general ward. But on Friday, he started to go down badly," Gallimore disclosed.
Born in the Kingston community of Greenwich Town, 1945, Holt has left a massive catalogue of hit songs such as Stick By Me, Stealing Stealing, Ali Baba, The Tide Is High and If I Were A Carpenter.
Some of those songs were done with The Paragons, one of the rocksteady era's great acts.
Holt is survived by his wife Merl, three sisters, three brothers and 23 children.
