A summary from the chapter covering this in the Run to the Hills Biography: 1. The band decided that they needed to get a new singer. 2. Rod wanted Bruce back but Steve was not into the idea - Rod had to convince him. 3. Blaze was fired (in january of 1999) before Bruce had officially agreed to rejoin. 4. It is possible that the band would have started to search for a completely new singer if the meeting between with Bruce would not have worked out. According to Dave Ling, Bruce was considering the idea a month before: Blaze said that the rest band walked to the dressing room without him and didn't do an encore at the Rio show in december- so he felt that something was wrong, but no one told him anything.
