Career: Davison's first professional role was in Love's Labour's Lost at Nottingham Playhouse in 1972 and his TV debut came in a 1975 episode of The Tomorrow People. A lean spell followed (during which he spent 18 months working in a tax office in Twickenham), but his big break came in 1978 when he landed the role of Tristan Farnon in All Creatures Great and Small. In 1981, he took over from Tom Baker as the fifth Doctor Who, but quit three years later for fear of being typecast. Other career highlights include A Very Peculiar Practice, Campion, At Home with the Braithwaites, The Last Detective, The Complete Guide to Parenting, Distant Shores and Law & Order: UK. Throughout 2010, he starred in the West End production of Legally Blonde, and directed and wrote a spoof documentary called The Five(ish) Doctors to tie in with Doctor Who's 50th anniversary in 2013.

Career: The show A One Night Stand with Sean Hughes toured the UK and Australia, as well as performances in Los Angeles, Montreal and Toronto. In 1991 he made a brief but memorable appearance in Alan Parker's acclaimed movie The Commitments as a record label executive, before writing and appearing in the aptly titled Sean's Show for Channel 4 a year later. Other TV programmes followed, including Sean's Shorts, but it was his six-year stint as a team captain on the irreverent music quiz Never Mind the Buzzcocks that made him a household name. His dramatic acting has included roles in Murder Most Horrid, Gormenghast, Girl on a Cycle, The Last Detective, Coronation Street, Agatha Christie's Marple, and Round Ireland with a Fridge.

Career: In the early 1970s, McKenzie took over one of the leading roles in Stephen Sondheim's Company. And so began a long association with Sondheim's work. Her big break came in the mid-1970s in the musical review Side by Side by Sondheim. It was a big success in London and New York. During the 1980s, McKenzie won an Olivier Award for her portrayal of Miss Adelaide in Guys and Dolls at the National Theatre. McKenzie has also worked extensively on TV, notably in Fresh Fields and its spin-off French Fields, Blott on the Landscape and Cranford. More recently, she has played the title roles in ITV drama Marple and one-off BBC children's drama Gangsta Granny.
