July 3 [10:00 EDT] -- It turns out that the national urban festival tour known as Jamizon that we told you about last month is being organized by a group that includes NBA great Earvin "Magic" Johnson.

Jamizon, which kicks off July 23 in Jacksonville, Florida and wraps up August 24 in Concord, California, is scheduled to include Keith Sweat, SWV, Kenny Lattimore, Brownstone and the notorious Mark Morrison as we reported in June. Johnson himself will be hosting many of the events.

Johnson, along with Quincy Jones' Vibe magazine and other backers are obviously relieved that bad-boy singer Morrison has been released from jail and is able to participate in the tour. Morrison, best known for his hit "Return of the Mack," was in jail in his home country of England the past six weeks on a variety of offenses, including an attempted stun gun assault on a police officer.

Jamizon, says organizers, will "salute urban music and its impact on popular culture by showcasing

a celebration of urban music, fashion, sports and art." The sites will include interactive sports displays; food; film and video; comedy; art, memorabilia and fashion displays; and local musicians in addition to the touring celebrities.
