Here is my contribution.
First in with Video Killed The Radio Star.
Is there any more era-defining pop rock song for the 1970’s than “Baker Street” (outside of disco, which was an unfortunate bump in the road)?
Or a more memorable one than “Band On The Run”?
I know you are trying to worm your way into my good books with Band On The Run 
Holy crap…I swear I did not see that in your signature or whatever that’s called by your username until this post. Funny. But I wouldn’t mind being in your good books either though…but you have to start eating oysters.
If you had boobs there is every chance you’d be in my good books. I’m that shallow.
That signature thing- I’ve been trying to think of something clever to put there - which shouldn’t be difficult- but i think the Mods would look on me with even more disfavour if it was “Oysters Still Taste Like Shit”.
This is either '79 or '80 but I cannot pass up a chance to post Lakeside’s Fantasic Voyage. It has a stage full of sand-- FULL OF SAND!
Somebody stop me!
I told you to stop me! Now I’m blinded by the light.
Seriously, I’ll stop now.

Seventies music means goofball music, ergo Kung Fu Fighting or, even better, Ooga-Chaka-Ooga-Ooga…
Well, you have to stop now, seeing as how you’re all wrecked up like a douche in the rumor in the night. That’s a tough spot to be in.
No, I’m wrapped up like a douche in the middle of the night.
At least you’re not revved up like a deuce, another runner in the night.
But hey, the 70s?
You’ve all been misled about what 70s music was about. Let’s hope you won’t get fooled again.
I wonder just how many wrong interpretations of that lyric there really are?
