Jamaican Reggae artiste Mr. Vegas (third, right) and Guyanese Natural Black (second, right) pose with Mike Fung of Mingles Sound Machine and officials of Banks DIH at a press conference at Princess Hotel yesterday. The artistes are set to perform at a concert this evening to observe the 252nd anniversary of Guinness that was observed yesterday, Arthur Guinness Day. Local brewer, Banks DIH Limited, said the concert is a way of giving back to Guyanese Guinness supporters. The company made it clear that although the concert is free, only those persons who received tickets through the many promotions prior to the concert will be admitted. The show is billed for 8 pm at the Carifesta Sports Complex. Gates will be open to ticket holders from 5 pm.
