Has anyone heard of an artist by the name of London Island?

Question

I think they are a female group and they had a song in the game GTA: San Andreas

Answer 1

Can't say that i have.

There is also no band by the name of London Island in the GTA:SA game. In the game, on CSR the DJ mentions London island just before the song "Keep on Moving" by "Soul II Soul" plays so that might cause some confusion.

Soul II soul is a band from London so maybe it's them you're looking for.
