Welcome, The Doctor and K9!Enjoyable review.  A spoiler box was added to the mention of a particular (tense) scene.
It's one of Big Finish's upcoming "Bernice Summerfield" CDs, which I guess is a sort of "Doctor Who" spin-off range... So, um, yeah: that's me!
I"m especially looking forward to the DAVROS miniseries! One thing I like about Big Finish is their willingness to dig deeply into characters like Davros, the creator of the Daleks. If Book of Temptation is any indiction of your writing ability, I'm sure I'll love the Davros CDs. I'll get to the Benny story eventually. I bought Seasons 1-4 during the summer sale. I'm currently in the middle of Season 4.
its not all coberts music but there is plenty of it. one mistake i noticed, they were playing blue whale music in maggies coffee shop? i guess maggie jazzed up the place and installed a juke box and loaded it with the same popular tunes that the blue whale had!
