You're my sister you're my soul

You're my sister you're my soul is a song about friendship and the fact that sometimes people can be friends for a lifetime even if one person lives far away. I wanted to write a song about that situation since my wife has a friend back in the US and †hey are friends since childhood and haven't since each other for about 20 years now. But they still care for each other and they stay in touch with skype, email or phone.
