Worship TEAM ??

I've been struggling with a musical problem for a while now. A song that's being covered ( as in cover band ) requires from zero to all six of our stage musicians depending on which song we're learning/performing/leading. If the song requires one, I usually hear two. If it requires three, you can count on four. If the song requires a simple x_x_x_x_ fill you can count on XxXxXXx_xxXx or something equally confusing. If the instrumental part on the recording is too boring, someone WILL assuredly add a bunch of extraneous notes to it for their own enjoyment. If three notes will do, why not seven or eight? True story. How do you deal with a musician you love as a person but don't want to be on stage with?
