conclusion" that Kajanus had appropriated Kullervo as his own. Stunningly, Kajanus had mislaid the score following the 1905 concert, and a "nerve-wracking" hunt ensued. When searches of the Helsinki Philharmonic Orchestra and Music Institute libraries proved unsuccessful, a "wholly mystif[ied]" Kajanus began to worry that "some crazy manuscript collector [might] have purloined the score". His patience exhausted, Sibelius in his diary entertained the possibility of conspiracy: "Letter from [Kajanus]. He has not taken the slightest care of Kullervo or—this is more likely—one of the orchestral staff who belongs to the clique around him has burnt it". In December, Kajanus located the manuscript in his personal library. Around 1916, Sibelius deposited the manuscript in Helsinki University Library for safekeeping, only to sell it to the in the early 1920s in order to address his dire financial situation. A decade later, Cecil Gray, Sibelius's first English-language biographer and an advocate in Britain for his music, reported that Sibelius had told him Kullervo would likely remain unrevised: Nevertheless, in early 1935, as Finland prepared to celebrate the centenary of the Kalevala publication, Armas Väisänen—the ethnomusicologist and general secretary of the festival—secured Sibelius's blessing to have Kullervo third movement performed under the baton of Georg Schnéevoigt. (Väisänen had taken Schnéevoigt to the Helsinki University Library to examine the autograph manuscript; the conductor did not find Kullervo to be on par with Sibelius's mature works, and was only willing to conduct Movement III.) The concert was held on 1 March at the newly-built Messuhalli, which was "filled to the brim". The performers were the Helsinki Philharmonic and a choir drawn from the YL Male Voice Choir and , with the tenor (who substituted when the baritone took ill before the dress rehearsal) and the lyric soprano Aino Vuorjoki serving as soloists. In a review for Helsingin Sanomat, wrote that, given the caustic receives Kullervo received in 1893, Movement III "surprised and astonished with its clarity, simplicity and subtle beauty". However, he faulted the soloists as woefully unsuitable in terms of timbre and dramatic interpretation: "[they] did not do full justice to the composition". The final time that any movement of Kullervo was performed during Sibelius's lifetime was in 1955 on the composer's ninetieth birthday, when conducted the Turku Philharmonic Orchestra in Movement IV. However, in the spring of 1957, just months before his death, Sibelius arranged for bass and orchestra the baritone's concluding monologue—Kullervo's Lament
