Toby Keith fans took to social media Saturday to accuse the singer of being too drunk to perform during a concert at Klipsch Music Center in Noblesville, Indiana.

Attendees of the concert, part of Keith's "Shut Up & Hold On" tour, noticed that the singer seemed to stumble around on stage and forgot the lyrics to several of his own songs. In the video above, Keith doesn't sound great, but it's difficult to tell if he's inebriated. Still, it's clear that something was wrong.

Backlash on Twitter was particularly harsh.



Toby Keith has yet to publicly comment on the negative feedback. His tour will resume Saturday at the Washington State Fair.
