The challenge
My journey starts thirty five years to the day
Since Anarchy spread all throughout UK
Three-and-a-half-hundred miles I was launched
To where David Bowie's arachnids had spawned
The day I arrived I remember quite well
Sixteen years after Gabba Hey's farewell
My purpose to find if there's blue in this red
Was Marilyn right? Is this Rock really Dead?
And though made undone by what Jagger can't get
I'm sorry my name may have murdered your cat
Each time I complete my ellipse 'round the Sun
Tell me what tune do I no longer hum?
The hints
None, this time.
