Dave Grohl was convinced Nirvana's concert at the U.K.'s Reading festival in 1992 would be so disastrous, it would end the band's career forever.
The trio's headlining slot at the event has become one of the most famous performances in the outdoor event's long history.
But drummer Grohl feared the show, which kicked off when frontman Kurt Cobain was pushed onto the stage in a wheelchair, would ruin the group as the bandmates were barely talking at the time.
He says, "Kurt had been in and out of rehab, communication in the band was beginning to be strained. Kurt was living in L.A., Krist (Novoselic) and I were in Seattle. People weren't even sure if we were going to show up. We rehearsed once, the night before, and it wasn't good. I really thought, 'This will be a disaster, this will be the end of our career for sure.' And then it turned out to be a wonderful show, and it healed us for a little while."
