Good Dave.
I haven't played a Uke at an Open Mic, I used to go to some and perform some songs with my Guitar but not for a few years now, I've got a Tenor and a Baritone with a pickup and EQ so should give it some consideration. I haven't played my Guitars much for quite a while, for me I need to apply myself to a few things including songs on Uke, Guitar, as well as other things too, it's a struggle sometimes but keep at it and try to fit some in regularly at least some each week, I've let my Guitar go too long, but I have been enjoying my Ukes, getting focused and staying focused can be a challenge for sure, and it's not just the music and songs, spending time figuring out recording and technology and other stuff takes time and effort too, so admittedly there's quite a bit involved in it all, and it can be easy to lose your track during difficult times many of us know. I'm getting my dentures next week, so I'm gonna have to practice speaking and hopefully singing again, have to see how that goes, so I don't even know what to expect in the future just yet.
Have you thought much about participating in the Seasons Of The Ukulele , you can find it in the contest section, there's a theme each week which is good motivation to find a song you possibly might not usually play, or maybe one of your favourites, it's good you would probably like it, good for your Ukeing.
The Music and Songs and the enjoyment at times makes it worthwhile, and it's always good when things go right and you can relish in your progress
and of course cherish those good times.
