Everything really has changed for Taylor Swift and Travis Kelce since last summer.

On July 6 the power couple—who are coming up on their one-year anniversary—shared a moment at the final Amsterdam Eras Tour concert that was so intimate, you would never guess they were in a packed arena with around 55,000 spectators—and I’m not even talking about their latest joint exit.

For the first time in 16 years, Swift performed “Mary’s Song” from her self-titled debut album, released back in 2006. Despite its age, the deep cut has come to represent Swift and Kelce’s relationship to many fans thanks to a particularly prophetic lyric—which she made sure to include in the surprise song mashup with “Everything Has Changed” and “So High School,” a song largely believed to have been written about Kelce for The Tortured Poets
