Kate

The new Controller of Radio 3, Sam Jackson, is having his first go at a presenter transition, and is taking it gently.  Composer of the Week is to be shared between the Venerable Donald Macleod, approaching 65, and Kate Molleson (age unverifiable - see, we can all do transparency). 

Donald, from Kirkintilloch, parlayed a degree in psychology and arts from St Andrews into a job as a BBC studio manager back in 1977, became a Radio 3 presenter in 1982, and has been presenting Composer of the Week, five days a week, year round since 1999. Composer of the Week, boldly rebranded from This Week's Composer in 1988, is, if you accept the basic continuity, the second longest running radio show after Desert Island Discs, and will hit its 80th Anniversary in August. 

In the modern "Across the UK" BBC, Composer of the Week is produced from Bristol by BBC Audio, who occasionally send a producer to that London. In the pandemic, it came from Donald's north London home. Kate, who has a little Montreal Canadian in her accent, is based in Glasgow, so that all makes sense. Kate is familiar to Radio 3 audiences, but she also writes books and music criticism; one hopes HMRC don't now challenge her freelance status.
