The snow's getting to you, Gary.
At church I'm the music director, choir director, minister of music - but everyone calls me the organist. It all pays the same.
I think single performers are always going to be called OMBs as long as we play for the public. What do you put on your business card - keyboards/vocals; most do. How many put one man band; only a few. Yet that's what the average Joe sees and hears,therefore the moniker.
Taking a day off here to enjoy the last of the good weather in Michigan. I see you've put a hex on us, so the snow will be coming soon. Cheers!
