Church Band Project Questions

[Thirdstageman]

Hello! I realize that this could probably be covered in several threads but since I'm using a Minidisk recorder, I thought it best to start here. I am preparing to record a church youth band and although I’ve done 4 CDs in the past, I still consider myself a novice and I would like to ask for help and suggestions. Here’s the situation: I have an MD8 Minidisk recorder that I will carry to each session. I intend to record the guitar and keyboards direct as well as the bass guitar through a Bass Rockman to help with compression issues. The vocals will be on 3 good microphones that the church will provide. They will come directly into the MD8 and then I will feed the stereo outputs into a sound system. This worked once before except for drums: they bleed over into everything with a mic and that’s my problem. Since I have 2 inputs left, what’s the best solution for miking the drums and minimizing the bleedover into the vocalist mics? I also thought about going ahead and recording as is with the bleedover and just going back later and re-recording the vocal parts without instruments? Any help would be greatly appreciated. Thanks!
