It's unclear how the fire started, but TMZ reports one bus went up in flames ... and the fire spread to the second vehicle.
The buses were parked and NOT occupied when they caught fire. According to TMZ, the buses are "crew buses" and not "band buses."
Thankfully the buses were not occupied, Band and Crew are Safe http://t.co/Kg9BEFxyRE— Foreigner (@ForeignerMusic) July 2, 2014
The bands are scheduled to perform together Thursday in New Jersey.
To remind you of Styx's greatness, their hits including "Babe," "Renegade," "Mr. Roboto" and "Come Sail Away."
As for the concert, the show presumably will go on.
