You may make fun of me for this but I'll be honest I haven't been to many, Andrew wk, flogging Molly, Cher (village people opened for her). But if I really thought about the one I will never forget will always be the first one on my mind of someone says "best or fav concert you been too"
Billy Ray Cyrus in Branson, MO when I was 9-10. It was amazing, got an ear infection from swimming the day before hurt like heal but it was worth it watching him sing ache breaky heart.
