Since Mojo hasn't gotten to this yet, and I hadn't watched the video before (I could already play the song when I came here) I can say yes, yes he does he played a B but said B flat. Whoops I also notice that over "No one waiting by your side" when I play this song, I play A - D - E not C - D - E. I kinda like the C so I'll have to have a play it again and see which I like better!
Welcome to the forum and have fun!
