Over 25 years ago I watched Nirvana play at the ANU Bar from outside.
I didn't join the crowd who pushed through a window and into the gig. I stayed outside and watched from the beer garden, then was surprised when the band emerged for a breath of air before returning to play an encore.
Kurt Cobain avoided eye-contact but I did get to enthuse with Krist Novoselic and Dave Grohl about the show and asked the former for a plectrum. You can see the orange guitar pick on the Nevermind cover in this photo.
Just now I spotted this photo of a ticket to a show featuring Nirvana from January 1992 and was excited to see it's accompanied by another orange guitar pick.
