Four years ago when I was new here this was a popular and fun thing to do. Pierre/ Fiddlerman made a jam with Fiddlerman video. Twinkle Twinkle. there is also a how to play Twinkle video. So after you learn to play you can jam with him.
I did this back then. I am so glad I did. I am going to do a "four years later video" one of these days and I think it will be so so very fun.
Here is a link to the jam video
