Jimmie Allen's Bettie James Fest is more than just a music festival. ET spoke to Allen backstage at this year's festival in the country singer's hometown of Milton, Delaware, where he shared the deeply personal meaning behind the second-annual celebration — named in honor of his grandmother and his father.«My grandma and my dad made me who I am, and for me, their names Bettie and James are more important than the name Jimmy Allen, at least to me it is because it's one of those things where this place made me who I am,» Allen explained.
