Frazer, who played Second Doctor companion Jamie McCrimmon in Doctor Who on television and in many Big Finish audio adventures, guest stars in Bad Faith, by Nev Fountain, as Bax Spendlove, a charismatic spiritual leader who Vienna encounters during her latest assignment.

“We were thrilled when Frazer agreed to join us in studio for a day to record an episode of Vienna,” says producer Mark Wright “He’s such a big part of Doctor Who, and brings such a sense of fun to a recording session, along with a great deal of experience. And it’s thanks to Frazer that we have the wonderful Chase Masterson as our series star – the two met on the convention circuit in America, and it was Frazer who introduced Chase to Big Finish. And we’re very glad he did!”

Frazer takes up the story: "I was horse riding with Chase and told her I was doing an audio recording, and remarked, ‘Chase... you have a good face, ideal for audio.’ She nodded in agreement, then realised what I had said… I galloped off double quick!!”

“It was great to see the two friends reunited in studio to record Bad Faith,” continues Mark. “We kept it a secret from Chase that Frazer was going to be joining us, and it was a delight to see her reaction on the day when he arrived. It made the recording day very special.”
