# Sigma Fields

may sing to tune of "Strawberry Fields" (John Lennon, Paul McCartney)

Let me take you down, 'cause I'm going to the sigma-fields
Lebesgue things are real, and nothing to get hung about
Sigma Fields forever

Living is easy with sets closed, and understanding all you see
Probabilities map to zero-one and it all works out, that's what matters most to me
Let me take you down, 'cause I'm going to the sigma-fields
When things are Borel, there's nothing to get hung about
Sigma Fields forever

Sets of sets are events, I mean it must be probability
That is you know it can't go negative or over one, that is I think it's not too bad
Let me take you down, 'cause I'm going to the sigma-fields
When things are Borel, there's nothing to get hung about
Sigma Fields forever

Always, no sometimes, probability, but you know I know a gambler's scheme
I think I know the mean, but the measure is all wrong, that is I think I disagree
Let me take you down, 'cause I'm going to the sigma-fields
Lebesgue things are real, and nothing to get hung about
Sigma Fields forever
Sigma Fields forever
Sigma Fields forever
