I did the originals thing for ten years with various bands and every time (most of) it was on me. The last band was the final straw - I was arranging every rehearsal, booking all the gigs, writing all the music and running all the stuff online! Rest of the band just needed to turn up when due! I quit the band saying you guys couldn't organise a reading club in a library... one month later the band collapsed.
Currently bandless but much happier for it. I have no problem helping out but when everything is on my head, as soon as something goes wrong, it's all my fault. A band is a team not a dictatorship.
