Your snake being 5 foot long is definitely a few years old. It appears it is comfortable in a relaxed and calm environment. So relaxed the previous owner used it as an ambassador to educate children on the beauty of such a wonderful creature. I'm not going to ask nor do I care what type of dancing or performances you do. I will caution you though that taking a mature snake out of it's comfort zone will result in a bad experience for your snake. If your snakes experience gets bad enough she will undoubtedly share her bad experience with you with a bite. Not sure if that is what you are looking for in your performance with her but no doubt your audience will have something to talk about and may even ask for an encore.
