Rapper Kool Keith responded Monday (June 28) to reported rumors that he recently was committed to a mental hospital. He said the erroneous allegations stemmed from a former associate's lying about him to European concert promoters. "It was made up," he said Monday. The former Ultramagnetic MC was said to have bailed out of his scheduled Glastonbury Festival appearance Sunday (June 27), but his manager said he had never been confirmed for the lineup. Reports surfaced Monday that industry insiders believed Keith missed the concert because he was institutionalized.
