Taylor Swift gave an emotional and heartwrenching performance of her new single, ‘Ronan,’ at the Stand Up 2 Cancer telethon on Friday. Looking like she'd already been crying, she starts to sing-- and the lyrics are what will get you! Warning:  I lasted about 10 seconds before I needed a tissue.

 

Swift penned 'Ronan' about 4-year-old Ronan Thompson, who died in 2011 after battling neuroblastoma.  She first learned about Ronan by reading the blog his mother, Maya Thomson, wrote. His mom also co-wrote the song.

'Ronan' is told from her perspective:

I remember your bare feet down the hallway / I remember your little laugh / Race cars on the kitchen floor / Plastic dinosaurs / I love you to the moon and back. … Come on baby with me, we’re gonna fly away from here / You were my best four years.

See, I tried to warn you!

All proceeds of ‘Ronan,’ which is available on iTunes, will go to fighting cancer.
