How do i contact a band for a charity performance?

I am a teenager with Cystic Fibrosis, and am interested in throwing a huge charity event to raise money for research. I want to contact a band (Forever the Sickest Kids) and see if they are even interested in performing. I would like to know how to contact them and hopefully be taken serious. Thanks for the help!|||It is not as hard as you might think. All you need to do is send a letter to the firm that manages the band. If you don't know who represents them you might try http://www.whorepresents.com/. lol no it's not a place to by whores as presents as their horrible domain name would appear. Getting in touch with the manager is the easy part, but getting them is the hard part. usually these things have to be booked years in advance due to busy schedules.
