Big Machine’s Tim McGraw recently joined Spotify for its latest episode of The Drop In. Surprising a group of healthcare and hospital workers during a virtual work call, the country superstar dropped in on the nurse staff at Virtual Health in New Jersey.

“I just want to thank you for all the great work you're doing, on behalf of me and my family, and most importantly for me it's an inspiration for my daughters,” said McGraw to the nurses before performing an acoustic rendition of “I Called Mama.”
