Those who were hanging out at the small New Orleans club, BJ's, the other night, got quite the pleasant surprise when Robert Plant showed up unannounced and performed there.

According to ultimateclassicrock.com, on July 15, Robert Plant played for two hours with the night's expected headliner, Guitar Lightnin' Lee.

Describing it as “amazing,” one YouTube user....called the show a “blues jam that included 12-bar and shuffle versions of ‘Black Dog,’ ‘Since I’ve Been Loving You’ and more.”

Plant is currently on tour down south, playing Atlanta, Georgia tonight.
