At one point in April 1997, Shaquille O'Neal took a break from his own recording session in the same building and rapped over some Guns music. "I saw Guns N'Roses listed on the bulletin board in the lobby of the studio so I stuck my head in to check it out," says Shaq. "They asked me to join them, so I started freestylin' over their track. It was the first time I ever performed with a rock group, and it felt good."
