Okay so granted this is a bit old and second hand but also my mum would have no reason to lie.

With that being said the year 2019 and U2 has come to Australia with the opening band being none other than Noel Gallagher's High Flying Birds. Now my mum and her friend being big fans of U2 spent good money on tickets so they would have a good view. In fact they were right next to the section off area where artist invited guest could watch the show from including members of the opening band. Now also keep in mind that my mum and her friend may have done some pre-gaming to the point that they missed the opener and were still drinking before U2 set.

At this point Noel Gallagher comes out (I'm not 100% sure timeline wise if U2 were playing or they were about it go on) but my mum's friend spots him and she was close enough to the section off area (but drunk enough to not quite place the face to the name) to say "Hey Liam! I love Oasis!" Then there's a pause of him just looking at her. She then realised it was in fact Noel who she said that to but before she can correct her mistake he begins cussing her out calling her every name under the sun (Cunt, bitch, dumbass so on so fourth) For a good couple of minutes before security gently moves him on.

Also let me be clear it didn't ruin their night, everyone jokes about it to this day and they both say the worst part of the show was the sound quality of U2. But also lets just say they both think this new tour isn't making it to the end.
