Update (8/25): Alright, Swifties and Morissettians—we've got a minute-long YouTube video that might not disappear. Watch it up top and scan down for the full story, including appearances from Ellen DeGeneres and the Dixie Chicks' Natalie Maines.
Original story (8/25): It's already been written in the music history books how Taylor Swift brought out between one and 10 famous people on basically every single stop of her 1989 Tour. Thursday night's edition was probably the biggest yet, and possibly as big as it'll get: T-Swift teamed up with Alanis Morissette to cover "You Oughta Know," the lead single from the timeless Jagged Little Pill album, which turned 20 (!) this year. (Check out our retrospective conversations with female artists like Slutever, the Veronicas, Eden xo and more.)
Universal Music Group has been yanking the YouTube clips of the performance, so for now you can enjoy a solid Instagram clip, above, and nice little Vine of the experience, below.
Until the audiovisual internet deities grant us the privilege to watch the full live performance (is Taylor making a 1989 Tour concert movie? She's totally making a 1989 Tour concert movie), enjoy our dual celebrations of Jagged Little Pill's 20th birthday.
And Alanis wasn't the only awesome guest to grace Taylor's stage at the Staples Center in Los Angeles; Ellen DeGeneres was in the house, to rock the catwalk for "Style"...
...AND Taylor teamed up with Dixie Chicks lead vocalist Natalie Maines for a cover of "Goodbye Earl," the 2000 single about murdering an abusive husband. Very on-brand.
