Fans of rocker Sammy Hagar now have an opportunity to join the former Van Halen frontman on stage when he comes to their town.|

The vocalist's official website, www.redrocker.com, is inviting fans to participate in a unique contest in which five winners in each city where his new single "Both Sides Now" hits No. 1 will be able to get on stage with Sammy for his "Marching to Mars" encore. To enter the contest, visit the Red Rocker website and follow the instructions. (Seth Hindin)
