Some Tv
by: Jon AndersonSomething in the dark is staring much to bad beginnings
Gangs of hungry kids are out stealing all the winnings
Strip the tourists on the floor, he is left with nothing
All he's got is life, his soul and bad dreams ever more
Someone in the dark is fixing dynamite, destroying
Put it in the main street where the shops are full of bodies
Agents have protection, cold religious killing
Market their releases though they're sent from heaven's door
Now we're not blind, now we can see
The truth is out, on your TV, on your TV
See it every day we focus CNN for dinner
Not so many killings everybody is a winner
Down in the dark the main street for the power and the glory
Must be something on the news to set our hearts on fire
We're not blind, yes we can see
The news is bad, the big TV
One thing hits me more and more, I know you're gonna get it
Good news doesn't sell at all, no point in trying to tell it
More and more you realise good news is not important
Look around there's so much more, my TV is distorted
Don't be so blind, yes you can see
Distorted minds, on our TV
One thing hits me more and more, I know you're gonna get it
Good news doesn't settle all, no point in trying to tell it
More and more you realise good news is not important
Look around there's so much more, my TV is distorted
Don't be so blind, yes you can see
There is good news, on your TV
So this morning I went to turn on my tape
On my Magnavox colour TV
It turned around and said "good morning Jon
How are you today, today"
Are you ready for some football?
Are you ready for The Price Is Right?
Are you ready for some football?
