In addition, I just saw this video, and thought that it was worth sharing. From the video's description:
Ippenya Is Playing For Change Too doesn't pretend to copy the initiative of the organization "Playing For Change".
We borrowed the original name of "Playing For Change" without asking, although we are not related to the organization.
We truly appreciate their giving us motive to create this video clip.
Presented by ippenya, a sound production company who has concept of leaving every moment to the fullest that comes only once in a lifetime.
Since the unforgettable sensation of "Playing For Change | Stand By Me" at first sight inspired us to take a creative action, something has been changed.
