That would be nice, Bill. But I've often found that even when the sound was great live - guitar and vocals evenly balanced, frequencies adjusted right, volume just right for the room, the recording device (be it my MacBook or someone's video camera or a tape recorder) didn't capture the same sound.   That can have a lot to do with things like direct-ins, mic placement in relation to the recording device, etc.

For example, in this clip of (mainly) Big Mick singing "Caledonia" , the input device (MacBook) was too close to me and some others in the room and too far away from Mick. So his voice comes over strong, but the guitar doesn't, and some of us singing or whistling along were picked up too well.   Same thing happened in the Getaway concert when the audience was singing along. The voices of people sitting near the laptop mic were picked up louder than ideally, relative to the on-stage performer's voice/instrument.
Of course, it helps to have separate tracks recorded for the various voices and instruments, but sometimes the convenience of a portable, all-in-one recording system trumps most other considerations. :)
