Walter Carlos no longer exists
He's in Elysium
But let us imagine him in our space-time continuum
Walter Carlos!
International transsexual composer of that glorious epoch
The high analogue synthesizer
Baroque!

He is now to be
Known as Wendy
Had a gender operation done
Just after making Switched on Bach, Volume 1

And when travelling through time is possible
Wendy can enter a wormhole and go back to the future to marry Walter
A few baroque summers earlier
A couple of models of Moog back in time

(Sung in a round:
Fine fine fine
In the summertime
Singing tra-la-la-la-la
And be fine in another time)

Unfortunately
Einstein informs us
That when time travel is finally possible
There will be no returning to periods previous to the point at which time travel first became possible!
So like Walter Carlos until such time as it's feasible
We'll have to restrict time travel to the realm of the musical
