Grammy-winning R&B singer Anthony Hamilton has serenaded many a female fan from the stage.

Now, Hamilton and The Hamiltones are getting praise for serenading, well, a goat at the Indiana State Fair. Watch the video below.

The impromptu performance has burned up social media, with many fans saying they couldn’t get the tune out of their heads.

“Whose billy goat is this?,” the singers deftly harmonize. It’s like church at the state fair as Hamilton chimes in with “baaa, baaa, baaa.”

It's even started a hashtag #WhoseBillyGoatIsThis.

The goat, though, seems more interested in getting more food than hearing Hamilton and The Hamiltones sing.

Ah, critics.

Hamilton plans to hit Augusta on Oct. 16 during his fall tour with Lalah Hathaway and Eric Benet. More dates will be announced.
