Entry Video

After having a little look around, I can't seem to find a video tutorial for the song/riff you play on the first screen. This maybe because I just simply don't know what I'm really looking for, due to not knowing the name of it, or it maybe because you haven't posted it.
If it was the latter, please can I request you to post it, as I would be keen to learn it. Or if it is already on the site, could you please let me know which section I could find it under, or post a link.
If it is neither of these reasons, but just that you would like to keep it to yourself, could you just let me know so I don't end up going mad trying to find it.
Many thanks,

Steve
