Taylor Swift gifted tickets to Friday’s show at Lincoln Financial Field to a mother and friend whose inspired one of the most heartfelt songs in Swift’s catalog.

In “Ronan,” Swift channels the emotions of a grieving mother who just lost her young son.

I can still feel you hold my hand, little man/And even the moment I knew/You fought it hard like an army guy/Remember I leaned in and whispered to you?/Com on, baby, with me/We’re gonna fly away from here/You were my best four years.

The song captures the real-life experience of Maya Thompson, an Arizona mother who lost her son Ronan on May 9, 2011, three days before his 4th birthday. He died after being diagnosed with Stage IV neuroblastoma in 2010, a deadly form of childhood cancer.
