The Diary of River Song

The Diary of River Song was an audio series produced by Big Finish Productions beginning in 2015. It starred River Song, played by Alex Kingston.

The first series featured Paul McGann as the Eighth Doctor. The second series featured Colin Baker as the Sixth Doctor and Sylvester McCoy as the Seventh Doctor. The third series featured Peter Davison as the Fifth Doctor.

It was Steven Moffat's idea to make River team up with previous Doctors on these boxsets, so she would work "her way back down his timeline". (VOR 95)
