The continuing interest in the Early series of Doctor Who is considerable both in the UK and around the world. There are Appreciation Societies, numerous websites and large conventions for the show's aficionados which Peter sometimes attends.

All About Peter as Steven Taylor
Although the video of the early shows has long since disappeared, the full audio of the shows still exists thanks to fans recording the programmes off-air when they were originally shown.
Mark Ayres and the BBC have been restoring and remastering these recordings to produce a series of high quality CDs. Those marked * above are complete and available through the BBC website, with The Savages due for release in November 2002.

Peter's Memories

"Following a couple of leading roles in TV plays I heard that Doctor Who was looking for actors who could 'move' to play giant butterflies and other insects in one of the serials. I went along to meet the director, Richard Martin, who very kindly told me that with the work I had been doing previously it wasn't worth me playing one of the non-speaking roles. However, he told me that if ever he was casting proper acting parts, he would think of me.

A few months later Richard was true to his word when he cast me as Morton Dill in The Chase. I was thrilled to be playing the part, but even more thrilled when I was asked to go with the Producer, Verity Lambert, for a drink at Studio 3, the pub opposite the Riverside Studios. I was dumbfounded when she asked me if I would be interested in joining the cast on a regular basis. Naturally I said 'Yes' and Steven Taylor made his debut appearance three weeks later.

Of all the serials the historical ones were my favourites - particularly The Massacre and The Myth Makers - and I have quite an affection for The Celestial Toymaker.

I finally left the cast of the show in June 1966.

More recently it has been a delight to be involved again. The remastered CDs being launched required some new commentary to add continuity to the original sound tracks and it has been a privilege to have narrated all of the stories in which I took part."
