Something I did recently - a very rough recording to get a local gig  - 8pm 21st March at The Grove Inn, Back Row, Leeds, West Yorkshire LS11 5PL, UK with Julian Socha and MGR Band.

Nice guitar work Andy and your voice carries through.  Your tempo is good here.  Do you ever keep time with your foot or do you always stand up?  The only thing I would suggest is try putting dynamics in your performance.  That is when you are singing, play less forcefully or more quiet and then you won't have to sing so loud and it might feel easier to you.  Then you could slightly raise the volume of your guitar playing while you are not singing.  Good luck and pardon the delayed response to your messge.

Thanks for the comments and advice, Corey.
