Travis went on to gush about his musician son, posting a series of throwback photos from Landon’s childhood and adding, “So proud of the man you’ve become and everything you’ve set out to accomplish and did. You are the best son and brother anyone could ask for. I love you always and forever my boy and cherish every moment with you.”
