Salt Palace history in Salt Lake City. Tickets for the June 18 concert were sold out in a record 1 hour and 20 minutes after the box office opened. Rehearsals for the Rhythm Nation Tour were held in Los Angeles. Jackson then rehearsed in Pensacola, Florida for two weeks before the tour kickoff. Jackson surprised the people of Pensacola with a concert that was announced only one day ahead of time. The $10 tickets, limited to a four per person, didn't go on sale until the morning of the concert. All 7,600 tickets were sold within three hours. Another 1,000 tickets were given to local charities. Jackson donated over $1/2 million to fund education projects from concert proceeds and also donated 25 cents from each ticket sold to the Cities in Schools program, which works to prevent kids from dropping out of school. After the tour ended, she gave $500,000 to the United Negro College Fund in the form of a "Rhythm Nation Scholarship". Jackson's first show for the summer tour, Saturday June, 7 at the Tacoma Dome in Tacoma WA, sold out so fast that she quickly added a second show – to be performed the day before, on Friday June 6. At the Saturday show, she had the world premiere of the video for "Black Cat" that had been filmed the night before. Jackson was scheduled to play Philadelphia in March but somehow the people who manage the Spectrum arena doubled-booked Jackson's show and a WWF match on the same night. The sold-out show was rescheduled in August. Jackson's four Los Angeles shows sold out in 48 minutes. Jackson had to reschedule her appearance at Byrne Arena in East Rutherford, New Jersey from September 8 to August 30 because of her performance at the 1990 MTV Video Music Awards. The opening act throughout all dates of the tour was the tour's musical director, Chuckii Booker. On the Show in Munich, Germany it was Johnny Gill. Jackson had to reverse the decision to use a live panther on the show after several incidents, including the panther urinating on stage. Citing concerns from fans, and her own love of animals, Jackson eventually did not use the cat in the summer leg of the tour. Jackson spent her 24th birthday at Tokyo Disneyland. Janet plans to release the "Rhythm Nation 1814 World Tour" on DVD or package it with an upcoming
