forgot one more to make it 11!!
Billy Porter - Mick Ronson

I cant think of a list but here's a couple that spring to mind.

Definitely Mick Ronsons-Billy Porter

Big Big Deal- Steve Harley & Cockney Rebel

Sex Bomb Boogie-Sigue Sigue Sputnik ( Very "Bolanesque" but was only released as a video single ! )

1. Sebastian - Cockney Rebel
2. Heroes - Bowie
3. Magnificent - U2
4. Sartorial Eloquence - Elton John
5. Complete Control - The Clash
6. Rust - Echo & The Bunnymen
7. Like A Hurricane - Neil Young
8. Breaking Point - Bourgie Bourgie
9. The Greatness & Perfection Of Love - Julian Cope
10.Happy Ending - Joe Jackson

Some of them were minor hits, all of them should have been MONSTERS!!!!!

No time to compile a full list now, but a couple of tracks spring to mind.

The first was a song called 'Mister it's your lucky day' by Gillian Burns. It was Kid Jenson' record of the week and so played each day. By Friday I was hooked, but after the 5 listens I don't think i ever heard it again. Might be dated by now (i thnk it was 1978), but would love to hear it again - but have failed miserably to find a download.

The 2nd track was also a radio 1 record of the week, but again I don't think it ever charted. The song is 'I cheat and I lie' by Won Ton Ton. I would implore you to listen on youtube as this song should definately have been a monster.

Not quite a monster but on the lines of where are they now. There was a group called the Vetoes that played the Dog and Trumpet in Coventry in the early 80's. They had a fantastic sound and deserved to be a monster themselves but never made it.
I often wonder what became of them or if any of their recordings still exist?

World Party - Ship Of Fools
Steve Harley - (Love) Compared With You
Duncan Browne - The Wild Places
Metro - Criminal World
Roy Harper - One Of Those Days In England
Jake Thackray - The Bull (just to pick one out)
Clifford T Ward - Home Thoughts From Abroad
Eric Carmen/Raspberries - Overnight Sensation
Head East - Never Been A Reason
Brian Protheroe - Pinball

Kiki Dee and Linda Lewis should be in there somewhere perhaps....

....IMHO I think 'Compared With You' and 'Home Thoughts' are two of the best love songs ever written.

Never know, someday they could still be monster, monster hits bubbelah.

Some fantastic singles/music in the lists so far..
How could I forget Sebastian
and Big Big Deal ?. Whilst Like A Hurricane is a timeless classic! :)Rebel....ebay might be the answer for the Gillian Burns single?
Really impressed with GedKen's list,that Metro song is great and The Roy Harper track a real winner just like his magnificent When An Old Cricketer Leaves The Crease and Overnight Sensation was a real turntable hit around the North West in 76! My old mucker Graeme will be well impressed with that choice! Must admit I had Linda Lewis with My Friend The Sun in my original list she does a great version of the Family song!and how about How Glad I Am by Kiki?.GedKen who are Head East?
In the 1980's when local commercial stations could go their own way and not stick to a very narrow playlist each morning on Manchester's Piccadilly Radio's Breakfast Show with the late great Tim Grundy they had a Should Have Been A Monster feature where a track was played nominated by a listener..
most days it was the song of the show!
Off to play (love) Compared With You and Home Thoughts From Abroad that's some choice...
