Zac Efron Sings Beach Boys' 'Barbara Ann' on 'Conan'

Zac Efron wears a pair of Prism shades and a beanie while catching a departing flight at LAX Airport on Tuesday (March 6) in Los Angeles.

The night before, the 24-year-old actor appeared on Conan where he joined host Conan O’Brien and his band member, LaBamba, in singing The Beach Boys‘ “Barbara Ann”!

The impromptu performance happened after Zac recalled a story about singing in public. He shared that when he was 15, he and his drama class buddies sang barbershop quartet songs while enjoying some free time in Paris.

“We’d stopped the entire Champs-Élysées. There was a crowd of people around us. We stopped traffic. We were just being goofballs singing songs,” Zac said.

FYI: Zac is wearing Levi’s denim trucker jacket.
