Roller Derby Team Name

We've been assigned teams... now we have the task of picking a name. It's a lot harder than you'd think. We all got firmly behind one name, only to find out it's already in use. It's not agreeing that is our problem, it's coming up with an idea in the first place.

So here's the theme we want to run with: Rock 'n' Roll girls.

One of the girls has a gold lame cape, the rest of us want to do up old jean jackets with the sleeves ripped out and be rock 'n' rollers from various eras. Some will go psychedelic 60's, some will go 80s hair bands, I'm going to go with a 50s theme of course. The team colours are up for renegotiation if a name really doesn't suit the colours we've chosen.

Just so you know our taste, here are the names that were well-liked, but have not made the cut (due to already being in use by other roller derby teams)
Thunderbirds
T-Birds
Firebirds
Rock 'n' Rollers

Anyone have any good ideas that aren't already taken?
