I just came home and I had a great time! I did not bring the guitar, I need to feel more confident first, I have three weeks until the next jam. The house band was absolutely amazing and the band leader went around personally and introduced himself to everyone while explaining how it worked. The level of people performing was consistently very high, there were bassists, drummers, keyboard players, singers and harp players, even a sax player but surprisingly few guitarists. The place normally has around five guests on a tuesday night but was absolutely packed with people of all ages. All in all a great night and next time the guitar will tag along.
