my band has a few songs and we'd like to record soon

heres the problem, we have a pa system and 1 mic but how do i record drums(or do i need to buy seperate mics for them?)

and also is there a program that happens to be free or i can buy at a store that records each instrument seperatly like, if i record guitar first then vocals, then like drums the next day?

Everything you just asked has been answered in previous threads... and I'm talking about threads within the last week.

*wants to start seeing more ADVANCED recording technique threads.
I was once heavily prominent on these forums from 2004-2007, let's see how long I can stay now that I'm back.
