The purpose of my frienship's theme is not heroism (even if it will have heroic version). It's all about feeling, frienship feeling...something simple, pure, naive, that just talk about the true emotion between our heroes.

and I didn't hide the fact that this music is heavily inspired by Superman, nothing new here...but this is not the same theme, the second half part is completely new and there are some differences in the harmonies.

The thing that make it really close to Superman is because it's exactly the same orchestration.
