Was Olu Maintain denied a US visa?

Olumide Edwards Adegbolu, known as Olu Maintain, certainly sings with honey in his voice, but we wonder why his sweet voice could not convince those at the Walter Carrington embassy to provide him with a visa? Reports are that his popularity is spreading like wildfire in America, however even his apparent popularity has allegedly not been enough to get him stamped. Sources tell us that he had initially had his passport stamped and then went back there under a new name but forgot that well known proverb that a goldfish has no hiding place, resulting in him practically being thrown out of the embassy and told never to return there. Could such a story really be true though?
