Digging up some very old news, but I was going through
@IronCarnage 's bootleg repository, and was always curious about the South American '98 show where Maiden did no encore. Blaze said that was the first night where he got a little worried about his future in the band. Steve's story was that the crowd wasn't cheering, so that didn't warrant an encore. Blaze said there was plenty of cheering.
I'm assuming it was the Rio show in '98, since that bootleg ends at Iron Maiden, while the following two shows on IronCarnage's list are complete. While there's only a minute or so of post-drum bashing to end the song in the recording, the audience was going suitably bonkers. Unless that faded into nothing over the next few minutes...yeah, Blaze's story holds more water.
Sorry if this has been discussed--did a search on it, and it didn't come up with anything.
