I love Pittsburgh boxing more than anything and this is a good song by London based band The BibleCode Sundays. According to Wikipedia they play a mixture of traditional Irish folk music and contemporary rock music.

This video was posted just a month ago and according to Wiki The Pittsburgh Kid EP is the bands first release in three years. I found this via a school project and wasn't expecting much but this song isn't to bad.

It is a fitting song to the Hall of Fame fighter. This isn't their first boxer inspired song either. They have a song called The Cinderella Man about, you guessed it, Jim Braddock. That isn't a bad listen either.
