Aug. 25 (UPI) -- Taylor Swift took to the stage at the 2026 Grammy Museum Icons Sessions gala.

The singer-songwriter, 36, performed an Eras tour-style mashup of her songs "I Knew It, I Knew You," "August" and "All Too Well" at the event Aug. 18 in Los Angeles, a recording of which was released Monday on YouTube.

Swift, who wore a 1930s-inspired sage green silk chiffon dress from Doen, discussed the inspiration behind the mashup as she sat at the same piano she took on her Eras tour.

"It's songs that are connected to each other by the common theme of being about memory and reliving certain detailed memories of your life, and the significance of those memories," she said.
