If you have visiting musicians/choir, do you take it upon yourself to join in if you're one of the house musicians?
We visited a church this weekend where our choir sang. We have a drummer, a conguero and me - the keyboardist (so I run my own basslines). Well, when our choir got up to sing, I started playing and the house musicians took it upon themselves to join right in with their organ, bass and keyboardist.
My problem with this is that they don't know our arrangements of songs; e.g. during certain songs when we'd normally cut the music (like "He's Able" for one) they would keep playing and I'd have to cue them to stop playing with messes up the flow of the song. And them when we'd modulate on certain songs, they were a step behind because they didn't know when I was changing keys. And then their instruments were so loud that they were smothering me out.
I thought when visiting musicians come, you as the house would step aside and let them do their thing - or as a minimum play in the background. At least that's what we do at our church.
