Black Crowes

It seems Chris Robinson likes to be his own opening act. Literally, as it turns out. The Black Crowes frontman revealed himself to be a multi-talented, multi-tasker. While rocking the stage at the Jackson Hole Music Festival this week, Kate Hudson's ex-hubby also showed off his bar-tender flair, according to Page Six.

Not content to merely be the rock star headlining the event, Chris jumped to the aid of a couple of inept beer drinkers in the front row, who couldn't figure out how to open their beverages.

Not missing a beat, Chris grabbed a handy opener and flung it to the clueless clods...who turned out to be the organizers of the festival! Whoa, that inspires confidence. Let's hope the band's checks cleared.
