I suppose it just demonstrates that starting a band is more than a musical thing. It's basically a social experiment - you've got to find people with roughly the same goals and ambitions, and then collaborate with them and their personalities. Inevitably many experiments will fail, sometimes even though the music is good. But you will benefit from every jam session, even if it goes no further. It's just important not to get disheartened...so all the best for next time!
