I've been doing stand up now for around 18 months and believe I have a solid 10 minutes which I have been using for the past few months. I just wondered how long should I be using the same material and how often others write new stuff?
Stand Up Material
There's clearly a lot of debate going on regarding how best to answer your query.
We spent 18 months going round with the same set with just the odd addition. That was due to laziness and complete indifference to the paying audience.
It depends on whether you think you are an amateur or a would-be professional I guess. If you do a number of shows at nearby venues you WILL get the same people. Better to get new material.
