How is "I should like to express my appreciation to the President for his opening address and to all those who sent messages of condolence to my home town, Gothenburg, where 63 young people died recently in a fire." said in German?

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

Ich möchte dem Herrn Präsidenten recht herzlich für seine einleitenden Worte sowie die Beileidsbekundungen danken, die er an meine Heimatstadt Göteborg richtete, wo vor kurzem 63 Jugendliche bei einem Brand ums Leben kamen.
