The Final Friday/Sunday Night is Music Night on BBC Radio 2? 

Is this the last ever regular broadcast of Sunday (previously Friday) Night is Music Night? The slot will be taken over by Paul Gambacinni for a brand new show from 22 October 2023.
If so, that would mark the end of possibly the last Radio 2 show originating from its predecessor, the BBC Light Programme.
This show was a Doctor Who special, presented by Jo Whiley.
