Howling:River Song could be...

I think that river song is... Lucy saxon. Heres why: if it was lucy then the best man she ever knew was the master, bang goes a gun and he dies. She then proceeds to disturd his ressurection.

River says the doctor didnt teach her to fly the tardis, but in sound of the drums the master had it and flew it. he may well have taught her to fly it.
