Sibelius continued to make changes to the final version of the tone poem as he sailed across the Atlantic Ocean aboard the steamship "SS Kaiser Wilhelm II" and even during rehearsals in Norfolk, but these last-minute changes, Andrew Barnett argues, must have been relatively "minor", as the orchestral parts had been copied before his departure from Finland. Sibelius was delighted with the new piece, writing to Aino, "It's as though I have found myself, and more besides. The Fourth Symphony was the start. But in this piece there is so much more. There are passages in it that drive me crazy. Such poetry". Neither the suite nor the Yale version of the tone poem was performed in Sibelius's lifetime, receiving their world premieres by Osmo Vänskä and the Lahti Symphony Orchestra on 19 September and 24 October 2002, respectively.
