If they're just shopping for gigs an obviously-real drum track might be a plus, even if the sound quality is less polished.
After all, if the booking dude hears obviously-programmed drums on the demo he's got no idea what the band actually perform like, has he?
Assuming the drummer is good, I'd use the recorderman method. Use an audio-to-MIDI-note process to grab the drum hits (use eq filters to isolate the individual drums for this, then go through deleting any extra MIDI notes and manually putting in any which were missed). Trigger the samples from the MIDI notes, blend with the stereo recorded drums.
