This actually makes me a little sad. There was a time where, even though I was not 100% in, I loved my brother's and sister's in my cong and would have LOVED to have experienced something like this. I LONGED for things like this to happen at the kingdom hall. I would hear about other church's that had live music and thought that would be SO COOL to have. Something to brighten up a hum drum meeting, something to make me WANT to go and take my kids to.
I always thought that was a big mistake when the org went away from the live orchestras at the conventions. It made the different volunteers in the orchestras feel like they actually contributed toward the convention. The prerecorded Kingdum Songs sounded too canned and so impersonal. I even got a chance to play at a convention.
