Just had to hunt thru the lower depths of my desk to find 'em....
Thin Lizzy - Mirror Badge
The Who put the boot in - bought at Charlton May 1976
Curly Wurly - out chews them all.

Disprin,
Hack Artist
and
POW! - Batman and Robin Against the Bomb

1. Enamel 'head girl' shield - a 'souvenir' from a girlfriend
2. CND logo

1. A Pink Floyd badge with Gerald Scarfe's hammers from 'The Wall'
2. One with a painting of a magic mushroom in a field
3. A Led Zeppelin badge featuring Jimmy Page's 'Zoso' symbol

I still have my badges - don't throw anything out. Just cannot put my finger on them. These were definitely in my top ten:

Drink Vimto - red & yellow, in front of me now
Clash - from White Riot tour
Younger than Cliff Richard - from a birthday card

and I also wore one I quote all the time:
It doesn't matter who you vote for - the government always get in.

allas a 1 badge man, these I have sported with glee and pride number:
Hawkwind - that Silver Doremi badge
Brian Eno - Roxy Music fan club badge (I still have it, make me an offer)
The Dreadful Grate* - small skull with thunderflash and skeleton with rose crown/garland
Echo and the Bunnymen - Super Bunny, dark blue on sky blue (lost on a rather boisterous New Years Eve at the Toll in Embra) and Shine So Hard - small green
The Mission - 1st tour, 4 badges, only ever wore the Serpent's Kiss one
Psychic TV - test card logo (I made this when I worked in a museum that had badge making equipment, I was employed as a designer)
PWEI - one of their American Expressionist logos, I have two
PWEI - The Poppies are Crap! and On Patrol
Red Lorry Yellow Lorry - b+w words and Paint Your Wagon wheel
I seem to recall a UFO Hipgnosis logo, red on black and many, many others I lost in various flat/home moves. I still have an interesting collection but not what it could've, should've been.
sigh...

*can't abide their droll, bad country for acid casualties but you have to admit they had their graphic image sorted

Pink Floyd Dark Side prism
Op-art not-quite-concentric circles
St Andrew's saltire with 'FUCK OFF (i'm scottish)' written on it. I am, but I lived in north Wales at the time.

Here's some of mine.

They had their whole range of slogans badged up, from "If it ain't stiff etc etc" to, my one of choice, a small orange "Be stiff" with a round face on it, not unlike mine.
I also had a Moss Bros one, but can't for a second remember why they should have produced one.

Oo er etc. And an Emerson. Lake and Palmer (in the style of a crest). I also remember a Deep Purple one bought at Lewisham Odeon. And a Stones tongue bought at the Wembley Empire Pool.

For years I wore a donkey jacket bearing badges for Rock against Racism and The Clash.
My how my girlfriend at the time, later to become Mrs.Y rejoiced when that jacket was finally retired.

... honest !
Eat contents.
Bung empty bag into an oven on a low heat.
Wait a few mins and hey presto ! The bag will shrink to badge size.

They advertised in the NME and Smash Hits (and probably elsewhere) in the early 80's, had a monthly catalogue (B/W on dayglo paper) with hundreds of the buggers, which came free with each order or if you sent them an SAE. I used to take orders from everyone in my class to save postage - they probably wondered who this idiot in Norfolk was, buying 20-30 badges at a time... I've still got a box of them somewhere in the attic, I keep meaning to make a "picture" out of them all, another job I'll never get around to...

And to answer the original question, the ones I instantly remember were XTC, Siouxsie & The Banshees, and a dayglo pink & green Rock Against Racism...

I still collect badges. Not as much as I used to, the obsession is waning and I'm back on records again.

Not what the Americans call buttons but the metal pin badges. Disney ones. From the parks and around the world. There are specialist websites and pin-trading meets. But at least I have made lifetime friends around the world through this obsession and I am down to my last 2,000, including limited editions. (yeah still being suckered with that one...). HELP!

How about the silver cut out 'Steel Pulse' pin badge which I acquired from their LSU gig at the 'Starship Enterprise' Union Building, together with the obligatory 'Rock Against Racism'.
Both proudly adorned my student rags!

I am a free man.
Only for use on stripy blazers. Must be accompanied with a scarf.

I had the full set of Ian Dury &, Sex &, Drugs &, Rock &, Roll &. (The ampersand after Roll is correct). I gave them away a few years ago to a mate who was keen to have them.
My favourite badge was one given away at a Roy harper gig - Back To Reality.

I'm sure that I read that somewhere.

Otherwise, this is excellent stuff but could I gently nudge contributors back to the "randomizer" theme?

1, Nuclear Free Ambridge

2. I didn't Vote Tory

3. Pop! - Still have that one, batman (TV series) stylee graphic, red and white on black.

Donatello, TNMT metal pin
Metallica- Master of Puppets
National Union of Students
and, charmingly, '8 out of 10 kids who kill listen to Slayer'. Nice.
