Good luck!

I would add one more thing--not for your audition, but for your future classes.

Know your class demographics. In other words, if your class members are mostly over 50, go easy on the techno. I've also seen instructors provide a clipboard so that students can write down their favorite songs. How many times have you been listening to music and said, "that would be a great spin tune?" Happens all the time.

Remember, you are asking us here at TE, and we are all outdoor cycling enthusiasts. You will get students who do not like to ride outside, but I still say that making the class relate to real cycling is a good idea. It's gotten some students in a class I attend to get outside and ride their bikes. That's a Very Good Thing.
