I be fine; I'm gonna have a tree so fine; I'm gonna take my time; I'm dead in the sunshine

The story:

My older sister would sing these mistaken words at the top of her 13 year-old voice when it came out in the seventies. My older brother would smirk and say nothing. I think he told her one day in car pool. She insisted, of course, that her words were the correct version until she grew into adulthood. We now tease her about it all the time, especially when we get together in the summertime.
