I play in a band with two guitarists, a drummer and a singer. We practice one night a week for 3-4 hours. We've been playing together for a couple of years and we are all older guys 30's -50's. We all have pretty demanding jobs, and at times can't make rehearsal. Well we usually just can it for the week if someone can't make it and try again the next week. Well lately we have missed a lot of practice. What do you guys do when someone in the band can't make rehearsal? I figure that my options are 1) rehearse with the remaining members, 2) look for a fill-in for the evening or 3) do like we have been doing and just can it for the week. Any input would be appreciated.

and because of the travel and having a new baby, I'll be taking time off from my band until probably late October. While I'm gone, we decided it would be a great time to get started on recording a demo (possibly full length) CD -- getting the drum tracks recorded will take at least a couple of weeks (probably longer than that) and until I'm ready to come back, the other guys can put down tracks and I can eventually fill my part in.
