Mick Jagger and his bandmates may be nearing senior citizenship, but Super Bowl planners only want people 45 and younger to take the field during the Rolling Stones' halftime show.

The NFL is offering 2,000 people a chance to watch the Stones play during the Feb. 5 extravaganza. They will be expected to dance, sing and cheer.

"This is a once-in-a-lifetime chance to experience the Super Bowl from a totally unique perspective," NFL spokesman Brian McCarthy told The Detroit News.

People are asked to apply in groups of 20 or more and be at least 18 years old and no older than 45. Signup is under way on the Web site of Star Flow Entertainment, the company organizing the volunteers.

The NFL says the reason for the age cutoff is that the job is physically challenging. Volunteers must enter and exit the field quickly and be on their feet for long periods. They will not have seats and will wait in a tunnel under Ford Field for most of the first half.

Participants also must attend up to five rehearsals that could last seven hours each.

"You have to attend rehearsal and be able to stand for long stretches of time," McCarthy told the Detroit Free Press. "And you have to run onto Ford Field with 2,000 other folks."
