Do not worry about being a novice and fumbling mess.
I was a novice and fumbling mess once,
Now I just a mess fumbling?

Seriously
This a good session with good songs good singers and musicians of all levels.
with good but rare witty non offensive out bursts.

Even if I say so my self I think I have improved and got bolder simply by attending this and other session throughout summer and the year.
Regards Pierre.
