I know it may seem impossible that we haven’t already done a song together, because we have been friends since the dawn of time. Believe me. It’s crazy even to us that it took so long to do it. Just seems like it’s a meant to be type of thing. And now it is. Here. . I’m so proud of your reinvention Colson. You’ve always been a rockstar in everything you’ve done whether it’s acting, modeling, being an amazing father, or exploring other genres. But now you have a whole entire album full of songs that reinforce what we already know." (sic).
