Hi Kev
I only had time to watch the first two songs... I'll check out the rest later.
I've done a handful of solo acoustic gigs and don't really enjoy it. What has helped me a lot has been to try and think "why should anyone listen to me?" there are always far better singers and far better guitarists than me...so the best way for me has been to try to bring something different. I'm guilty of doing the things I'm now saying aren't such a good idea...like strumming the same pattern and doing it too fast and singing as though it's an ordeal that you secretly hope will soon be over is what I've often done...and I have to make a conscious effort not to do that. Having said that...if the audience look like they're loving it...then by all means carry on.
Now, I try to slow down and find a way of engaging people with the story I'm trying to tell. If there's a message in the song, try to make it easier to grasp and maybe find little ways of making people take notice. Stops when not expected can work really well...acapella sections too for example.
Just a couple of thoughts...not meant to be critical at all...it's really hard to do. Easy with a band...but here, there's nowhere to hide.
Best of luck with it.
