Why would you submit tracks made before the jam? The whole point is to make something in the specified time according to a specific theme.
If you weren't able to do it, why not just wait till the next one? This isn't a show and tell...

Yeah I want to make something within the time limit, but unfortunately I just can't do it during the day itself. I would wait for the next one, but no guarantee the timing will suit me again haha, as I had a lot of things going on with family at the moment. But I want to compose for a purpose, and I think participating in a jam like this would push my limit better than if I do something on my own without any purpose. I do agree this is not show and tell, but I also see it as a great opportunity to get feedback and learn from others.
