Gregory Isaacs lives on through foundation's charity work. Studio 38 was the last location the late Gregory Isaacs performed in Jamaica, so it was only fitting that it was chosen to host his birthday tribute party.  Many turned out to see reggae pioneers as well as up-and-coming stars pay homage to the 'Cool Ruler'.  'The Hat Affair', as the tribute was dubbed, did not disappoint. From the old to the young, many donned their felt hats and grooved the night away to some of Isaacs' classic songs.Cocoa Tea, George Nooks, U-Roy, John Holt, Luciano, Big Yute, Mikey General, Noddy Virtue, Hezron and QQ were just some of the artistes who took to the stage to pay tribute to Isaacs.
