Would It be computable?

All I have is a string of bits
Zeros and ones as the tape permits
It runs until it quits
Oh would it be computable?

Lots of symbols to designate 
Fetch instructions and automate
New write, new move, new state
Oh would it be computable?

Aow my Turing machine computer is a bustling mill
It will never halt until
It’s snowing in Brazil!

The read write head changes frequently
Left and right deterministic-ly
It sure looks like a busy bee!
Oh would it be computable?
Computable! Computable? Computable!
