AC/DC's Brian Johnson hitting the track at Daytona
DAYTONA BEACH, Fla. -- Brian Johnson is a typical red-blooded English/American male. He loves rock music, fancy cars and auto racing -- among other things. But Johnson, who became AC/DC's signature voice after the death of Bon Scott in 1980, is one of the most popular rock singers on the planet. He'll also be driving all night long as part of the 50+Predator/Alegra racing team during the 50th Anniversary of the Rolex 24 At Daytona Grand-Am race, beginning at 3:30 EST on Saturday.
