Ziggy Stardust

Ziggy played guitar, jamming good with Weird and Gilly
And The spiders from Mars
The single most important thing to note about this song is that Ziggy Stardust was one of David Bowie's more prominent stage personas, so this song is in many ways refering to himself. It may as well be "Bowie played guitar."

He played it left hand
Your left hand feels like a stranger. It's kinda like cheating.

But made it too far
Every guy has done this at least once. Messy.

Became the special man, then we were Ziggy's band
Bowie's the "special man" alright. It's pretty obvious every time he wears tights on stage.

Ziggy really sang, screwed up eyes and screwed down hairdo
Obviously just a trick to work screwing into the song.

Like some cat from Japan,
This line is a bit incongrous. While Japan is admittedly pretty messed up, the Japanese are also stereotyped as having small genitals. In that way, Bowie is clearly not like some cat from Japan.

He could lick 'em by smiling
A blatant reference to oral sex.

He could leave 'em to hang
Which would be the alternative to performing oral sex on 'em.

Came on so loaded man, well hung and snow white tan
This line is one of the most direct ways ever that David Bowie has sung about the size of his crotch. There isn't really anything I need to add here, those are the actual lyrics. You don't even need to play the album backwards.

So where were the spiders, while the fly tried to break our balls?
Just the beer light to guide us
We suspect that this was the point in the songwriting process where the drugs began to kick in.

So we bitched about his fans, and should we crush his sweet hands
Presumably the talk of crushing Ziggy/Bowie's hands is so he can't play guitar. The motivation for that may be so that the jealous band members would need to play with Ziggy's "guitar" for him. Wink-wink.

Ziggy played for time, jiving us that we were voodoo
Voodoo dolls are a very sensual sort of magic. Anything done to the voodoo doll is felt by the subject of the doll. This could create some very unique recursive sensations under the right conditions.

The kids were just crass,
You get a bunch of teenagers to go to a concert to see Bowie as dressed, or un-, as he was in the Ziggy Stardust days and you see if they aren't crass. Not a surprise.

He was the nazz
No clue.

With God given ass
Sex again. It could be that with our focus on David Bowie's Area, the secondary sexual characteristics haven't received the attention they deserve.

He took it all too far
Too far for what? Too far for a first date? Too far for the business/personal relationship that goes with being bandmates? Hmmm...

But boy could he play guitar!
His own or anyone else's. It's this skill "playing guitar" that forgives him for supposedly going "too far"

Making love with his ego, Ziggy sucked up into his mind
Any man with an Area like Bowie's is going to get ego issues at some point. It's inevitable.

Like a leper messiah
Not really sure what that means, other than it's a good line for Metallica to steal outright for the title of a song later, proving that Napster didn't invent music theft.

When the kids had killed the man I had to break up the band
A very deep and symbolic line about the loss of identity through fame and the dangers of self-absorbtion. Or maybe about the bloody murder of a rockstar by rabid fans. Either way.

Ziggy played guitar
And now the song has lapped itself. It can continue onward into infinity. Just like David Bowie's Area.
