Warren was great and truly made us feel like we were in "Margaritaville". I hired Warren for my wife's 40th birthday party in Virginia Beach. Warren kept in touch with me as the event drew closer, so I definitely felt comfortable feeling I could count on him. On the morning of the party, Warren said his voice was feeling a little weak, Warren assured me that we would have good entertainment no matter what. He actually had another singer come with him as a back up plan. Warren sang and played great!! (we also had a chance to hear Harry sing as well, he was good too). Warren was so laid back and interacted with everyone, including the kids.
