They only want you when you're seventeen
When you're twenty-one
You're no fun
They take a Polaroid and let you go
Say they'll let you know
So come on
Ladytron is a British electropop band that was formed in Liverpool in 1999. They took their name from the 1972 Roxy Music song, "Ladytron."
The lines quoted above are the lyrics of "Seventeen" in their entirety -- they are repeated seven times in the song.
Here's the official music video for "Ladytron." (Don't worry -- I don't know what the hell is going on in the video either.)
