Wow that was really great, in my eyes you are way beyond Grade 1 my friend. Steady rhythm and great vox as well! You mentioned you are more than happy to perform for your wife and pet, may I suggest widening up the inner circle to the whole Community and attending our Online Open Mic event happening in 3 weeks? More details below 
Btw saw more of your videos posted, just need to find a silent few mins to go through them all! However you seem like a fine player to me! All the best.
