I never knew my grandparents, so it's hard for me to hear songs like this sometimes. It might also be why I'm so excited when my daughters grand parents come to visit because it's something that is so special for them! Riley Green wrote his new song "I wish grandpa's never died" in honor of both of his grandpa's and it turns out that Brad Paisley is a HUGE fan of the song and asked Riley to come and sing it with him onstage. First off this is an amazing song! But look at how humble and excited Riley is to have such an endorsement from a legend like Brad Paisley! I bet he's still smiling from this night!
