Jimmy Fallon gives impromptu show at Amagansett bar

Late-night talk show host Jimmy Fallon jumped on stage Saturday  night at  Stephen Talkhouse in Amagansett, strumming on a borrowed guitar and taking the spotlight from the band scheduled to perform.

Fallon reportedly showed up at the bar and asked members of the band, The Black Petals, if he could join them on stage. Dressed in jeans and a striped polo shirt, Fallon took over the mic from the Petals’ lead singer to the cheers of a quickly growing crowd.
