“Sibelius and his wife Aino were in Gothenburg for a concert, the composer disappeared shortly before he was due to conduct. Aino found him, immaculately dressed in his white tie and tails, drinking champagne and eating oysters at a nearby cafe. Returning with him to the venue, she thought her husband was fine until he began the Oceantides overture. After a few bars, alas, he stopped the orchestra and started to give them notes … convinced that he was at a rehearsal.”
