“Technical issue on Saturday Night Live before Stevie Nicks' appearance interrupted the show

Eagle-eyed “Saturday Night Live” fans immediately noticed something was wrong before the show's musical guest, Stevie Nicks, made his second appearance. After a flurry of internet comments, it turned out that it was actually a technical issue that was quickly resolved.

The seemingly smooth The 50th anniversary season episode (which featured Oasis impersonations and a fantastic monologue from host Ariana Grande) experienced a speed bump just before Grande was set to reintroduce Nicks for her next song. The issue caused the show to put up a Nicks billboard for about 50 seconds while the emergency was being dealt with, then go into a commercial break.

Once things were settled, Grande appeared and reintroduced the legend. Shortly after the iconic guitar intro of “Edge of Seventeen” begins, Nick can be seen fiddling with the microphone pack on her right side, but it ultimately has no effect on the singer's performance.

It wasn't the singer's first time on the “SNL” stage. 41 years ago, in 1983, Nicks performed “Nightbird” and “Stand Back” onstage after completing her tour in support of her album “The Wild Heart.” The evening's host was comedian Flip Wilson.
