AUGGHHHH! I am freaking out because my two of my three guitarists can't make rehearsal this week. They are excellent musicians and know the songs, but I get really short of breath thinking about going into Sunday w/o proper rehearsal...and with both of them being very busy business people with young children, and the third being a very busy college student, this happens a lot. Factor in a keyboard player who subs at another church and sometimes I don't know who's coming or going.
Laying down an ultimatum is not an option; there's no one else to replace these folks (in more than the musical sense -- we've all become great friends). It's not as thought they're unreliable in the something-more-fun-came-up way, it's just that they all have soooooo many other things going on. *sigh* What's a worship leader to do?
