Most of the illusions used are either in public domain - or the rights are owned by their inventors. Almost all of the illusions in the Magic Show have been presented by other magicians as well. They change up the routine a bit, add their own style, etc. but the illusions themselves are easy to get the rights to perform.
I think the magic show could work with all different more modern illusions today as well.
Where are you looking to put this on? You would need a magic consultant!
Some people come into our lives and quietly go, others stay a while, and leave footprints on our heart, and we are never the same.
