Fans knew that Lil Dicky has something planned for his show in Ann Arbor before they walked in the door because of the following tweet.

I don't know that anyone would have guessed that Coach Harbaugh was going to get on stage and sing the National Anthem with Lil Dicky.

Dicky was definitely full of clues though as he posted the pic with Jim Harbaugh, then proclaimed that he was becoming a Wolverine.

Finally showtime came, and fans were treated to a National Anthem duet from Harbaugh and Lil Dicky.
