Is This a Guitar Cover?

I like to jam. I enjoy improvising and often times I won't recognize an idea until after I listen to it. I can't place where I know some of the music from in this particular improvised piece. It was fun to play and I am hoping somebody recognizes parts because it has been months and I just can't recall where I recognize some parts, especially the beginning. That is why the title is Is This a Guitar Cover? I assume there is some originality. Most of my music is original.
