I know Showbiz was also performed at MEN Arena which was the last performance. I'm sure both Showbiz and MM came up a few times though. Not just once.
There might be a chance to bring Showbiz songs back, but really with the exception of Sunburn a few times they've tuned out the Showbiz songs entirely. It just feels like they don't want to play them anymore.
Who knows, maybe like Cave one will come back for a short time, but I'm still not going to be expecting them.
