Let me see if I’ve got the timeline right. In February 2020, Joe Lazarus is the drum technician for Simon Dawson as they tour the United States with British Lion. Joe Lazarus was not the backup drummer during the Future Past tour due to commitments with Twin Atlantic and Phil Mogg. However, he continues to perform with the Iron Maiden cover band High On Maiden throughout 2023 and 2024, while also recording videos at Steve’s house in Essex. Nicko suffered a heart attack in January 2023 and informed the band via email the following day. On February 28, 2023, British Lion announced a 14-date tour across the UK and Europe between May and July 2023 and the dates matched the route of Iron Maiden’s tour. British Lion increases their activity in 2023 , but does not travel to North America for the 4 dates in 2023. Maybe Simon was around anyway? British Lion tours the UK in January 2024 and after that tours the world in close proximity to Iron Maiden for the rest of the year. Meanwhile, Joe Lazarus uploads his last Maiden cover (Seventh Son of a Seventh Son) on April 11th 2024. He is increasingly resembling an exact replica of Nicko, even mimicking specific gestures from the Maiden England video.
Now for the speculation part. According to Joes dad Steve Lazarus, Joe had been the backup drummer for the past three tours up until this point (January 2023), probably referring to the two separate Legacy of the Beast tours and perhaps the Book of Souls tour? Steve Lazarus left the Maiden camp somewhere just before Legacy of the Beast tour and is probably not aware of how the backup drummer discussion is shaping up from that point on, but Joe is working with British Lion and more interesting as Simon's drum tech. In February 2023, Steve Harris must have made the decision that Simon would be the new backup drummer as Joe wasn't going to be available for the tour. Simon likely spent February to May 2023 rehearsing the Future Past setlist and has since likely spent some time preparing Maiden songs from the first nine albums for the Run For Your Lives tour.
Is it possible the entire British Lion camp has rehearsed the Maiden set, just as Nicko used his band Titanium Tart to rehearse the Maiden setlist? Maybe David Hawkins and Grahame Leslie are guitar backups? I don't think Maiden will stop until either Bruce or Steve is done. In December 2024 Steve Lazarus had his online meltdown when the announcement was made, but Joe remained composed. Simon was announced only as the drummer for 2025, despite the tour being clearly planned to span 2025–2026. This may be due to his age, as he is only six years younger than Nicko. Perhaps Steve intends to give several drummers a chance, starting with the oldest as a logical choice. When the time comes to record a new album, it’s possible that neither Nicko nor Simon will be ideal candidates. It will be interesting to see if Joe continues to be involved during the 2025 tour, playing with High-On Maiden and recording Maiden-related videos.
