Summer nights, hot and humid, mean just one thing — it’s Proms season again. Sore feet, sweaty armpits, queuing outside the ladies loos, home on the Underground with a head and heart buzzing with Bruckner or Bacharach, Handel or Honegger. Just as special is the nightly feast on Radio 3 — a live concert, guaranteed every evening, and on top of that specially commissioned talks and literary events to get us thinking.
