Answer:
I am a rock group with four members. All dead one was assassinated.
Weight in my belly trees on my back nails in my ribs feet I do lack.
I can be hairy and itchy all over. I hang on a stick. I can be the scariest thing you have ever seen. I stand in the middle of nowhere.
I'm a word that is not even strange. What am I?
My head and tail both equal are my middle slender as a bee. Whether I stand on head or heel Is quite the same to you or me. But if my head should be cut off the matter's true though passing strange directly I to nothing change.
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
