Length of concert

Can anyone give me an idea how long the concert at the Meadowlands lasts? I am going on Thursday and I have to get a babysitter and want to give her an idea...

Thanks.

Bon Jovi have been playing for roughly 2 and a quarter to 2 and a half hours, they go on at roughly 8:30 pm so I would say you need your babysiter till at least midnight or one am depending on traffic and how far away you live from the Meadowlands. Thursday is the last show of the first leg of the tour so depending on how Jon's back is it may go longer.
