If you love Elton John, rock ’n’ roll and a fun-filled evening with friends — and helping a worthy cause — consider Rockin’ Out for Alzheimer’s. “Fundraising for this Alzheimer’s cause starts with the word ‘fun,’ and this concert is going to be an absolute blast,” said Chandler Dennard, event co-chairman. “This Elton John tribute concert is performed by Tokyo Joe Productions, a dynamic rock ’n’ roll band that co-chair Darron Burnette, myself and our wives started following about seven years ago when we attended a Hilton Head concert.”
