"I Always Knew I Had It In Me" by Masser and Goffin, 1977. Produced for the film "The Greatest" about the life of Muhammad Ali. I heard this song thirty years ago and only recently found it after attending a George Benson concert at the Sydney Opera House. The lyrics of this song have always spoken to me. This song is five minutes long, this is just a clip I created for my Skype account. The full version can be found by searching on YouTube.
