Well....in my book a Polka is traditional. I can understand a young person growing up in today's world wanting to put a new twist on the music but you have understand the customers view, they want to hear the music as they knew it when they grew up learning to dance and Polka is part of their heritage.
I played Big Band style music for 25 plus years for people that grew up during that era and I had to learn to play Polka like they wanted to hear it(my heritage is mostly English); the way it was as what they call; Old Time.
Our bass man played the Tuba when we player German Polka and Waltz. During a Polka with no warning he would blast out a loud "WOOMP WOOMP" and the dancers would laugh and dance a little harder; and then when our singer started sing in their language of German their eyes and faces would light up and the music filled their hearts with love.
