I'm even more confused about the name now. CF3 is usually on top of things like this, but he is way outnumbered.
Now how does the Encore part play in? Do they just assume the crowd will want to hear more when they are done with their set? In my concert going experiences usually encores are requested by the audience 
carnies usually entertain people at carnivals with an unusual talent or skill. the members of The Carney Encore are carnies that all work for the same carnival in MHK. In addition for working for the same carnival, these carnies also moonlight as musicians.
singer/guitar: this guy is the closest thing this carnival has to a bearded lady. when he's not performing for the crowds he spends his time cooking up corndogs for the carnival goers.
drummer: sometimes he sells the corndogs over by the dunk tank, but he usually works the front gate.
guitar: strongest man in the universe. he likes to pickup big, heavy things and perform various other feats of strength for the crowds. sometimes he wrestles our next carney/band member.
bass (stevesie60): last but not least, our very own, stevesie60. he makes and sells the world's best refreshments, which he sells over by the corndog stand.
