In today’s world, if it happens then it was also probably caught on video. No longer do fans hold Bic lighters in the air at concerts but they’ve been since replaced with smart phones.
Last weekend during a KISS concert in Montana, Gene Simmons made a slip. And a fall. Of course it was caught on video and later posted.
Two things come to mind while watching: 1) Thankfully a roadie was able to help Gene regain his feet. With the full costume and the added weight of a bass guitar, most anyone would be unable to reain footing, 2) Did Paul Stanley even notice? Or, care?
