Sean Rafferty chairs a seasonal debate at the Wigmore Hall in which four celebrities champion four Great Composers.
In respective corners:
The writer and broadcaster Germaine Greer for JS Bach, Guardian editor Alan Rusbridger for Beethoven, Michael Portillo MP
for Wagner and choreographer Siobhan Davies for Stravinsky.
The audience decides which of the four is the "essential composer".
At 2.00pm the programme will finish with a substantial work by the winning composer.
