Anthony Rizzo and Theo Epstein sing karaoke to AC/DC

Chicago Cubs first baseman Anthony Rizzo and President of Baseball Operations Theo Epstein seemed to be enjoying themselves in the below video as they belted out some karaoke to AC/DC’s “You Shook Me All Night Long.”

Joining Rizzo and Epstein on the microphone was blogger Dan Katz, better known as @BarstoolBigCat.

Blogger has epic day with BlackhawksBack when Epstein was with the Boston Red Sox during their run to the World Series title in 2004, he would routinely hang out with the players — some that were even older than he was.

Even while donning much more gray on the sides of his head, Epstein, 41, shows that he can still hang with the 26-year-old Rizzo — who celebrated his birthday over the weekend.

Give a listen to the full AC/DC version below.
