Armageddon the musical - Robert Rankin

From the point of view of 2050, you're history

Theological warfare.
Elvis on an epic time-travel journey - the Presliad.
Buddhavision - a network bigger than God (and more powerful, too).
Nasty nuclear leftovers.
Naughty sex habits.
Dalai Dan (the 153rd reincarnation of the Lama of that ilk) and Barry, the talkative Time Sprout.
Even with all this excitement, you wouldn't think a backwater planet like Earth makes much of a splash in the galatic pond.

But the soap opera called The Earthers is making big video bucks in the intergalactic ratings race.
And alien TV execs know exactly what the old earth drama needs to make the off-world audience sit up and stare: a spectacular Armageddon-type finale.
With a cast of millions - including you!
DON'T TOUCH THAT DIAL - IT'S GONNA BE A HELLUVA SHOW!
