I need well knows bands! to help me put together a show to raise money for pennies for patients!?

I'm not sure you're going to get a well-known band in that amount of time unless you have connections. However you could ask a well-known local band to perform (they're more likely to do it for free). Well-known bands need to be contacted probably at least 6 months in advance because of their busy schedules. You also might do some research and find out which band supports which charity and ask the one that supports your cause. Keep that in mind for next year. Good luck!
