Girls On Top

First it was Marianne Faithfull making off with what was supposed to be (soon-to-be-boyfriend) Mick Jagger's very first original song released with his band:


As Tears Go By (original release) - Marianne Faithfull



As Tears Go By (original writers) - The Rolling Stones



Then, it was Jane Wiedlin getting ahead of co-writer (and friend--with benefits?!), Terry Hall:

Our Lips Are Sealed (original release and original co-writer) - Go-Gos



Our Lips Are Sealed (original co-writer) - Fun Boy Three




And--with no romantic involvement whatsoever (that we know of!)--Cyndi Lauper gets ahead of the shaded one (posthumously):

I Drove All Night (original release) - Cyndi Lauper



I Drove All Night (original writer) Roy Orbison
