[Verse 1]
Twenty-four hours of every day
I'd walk on glass just to hear you say
Getting it on is like a drug to me
I want you baby, can't you see
I'm crashed and I'm crushed and I'm stuck on you
I'd do anything that you want me to
I'd crawl on my knees just to get to you
I close my eyes and girl it's true

[Chorus]
On a psychedelic space machine, galactic sugar high
Like a caffeinated satellite gone way past 99
Come on, be my
21st century girl, all outrageous, quite contagious
21st century, you got solar fire
21st century girl, sweet romancer, cosmic dancer
21st century sha la la la girl

[Verse 2]
Kiss this, you're blowing my mind
Never say never, but I'm taking my time
Girl to the world from the A to the Z
I fall for you so easily
Catch my breath because I know too well
That I just can't control myself
Realize we synchronize
It's only when I close my eyes

[Chorus]

[Verse 3]
Flying, flying
You take me up, you set me free
No time to breathe, just zero G
High, still flying, no gravity
She's flying

[Chorus]

[Outro]
21st century, sha la la la girl
She's a 21st century, sha la la la girl
21st century, sha la la la girl
She's a 21st century sha la la la girl

Def Leppard

In 1977, Rick Savage, Tony Kenning, and Pete Willis were students at a secondary school in Sheffield, England. They had a band called Atomic Mass. Lead singer Joe Elliott joined later that year, and suggested a new band name. Within 10 years, that name, Def Leppard, became one of the most recognised in English rock music. To date, they have released more than 40 singles.

Def Leppard was a definitive part of the new wave of British heavy metal bands in the late 1970s. Their first three albums had tremendous momentum, each outselling the one before. Then, after the release of Pyromania in 1983, drummer Rick Allen lost his arm in a car accident. The band stuck by him through his recovery and retraining.

When Def Leppard came back, they came back hard. Their fourth album, 1987’s Hysteria, was a hard rock masterpiece that took the world by storm. By then the music video had matured as a film style, and Hysteria’s singles and videos had enough pop, sex, colour, and glam to put it over the top. Hysteria was one of the biggest-selling albums of the 1980s.
