Answer:
I am a rock group with four members all of whom died in plane crashes. Who am I?
I have every color but no gold.
I am in the past never in the future. I don't exist but have existed. I saw what you saw and that is what I will ever see.
I go up when the rain comes down. What am I?
If you have me, you want to share me. Once you share me, you won't have me. What am I?
It flows out of the soil, It burns you if it boils, And holds us in its coils, More valuable than gold, As black as it is old.
