Where next for Radio 3? Last Friday was the First Night of this year’s Proms season but it was the last night at the Proms for Roger Wright, who for 15 years has masterminded the station and for seven of those 15 the summer concert programme as well. Rather surprisingly, and you might think ominously, no successor has so far been named to steer this most elegant yet vulnerable station into the digital challenges of 2015 and beyond.
